Evidence-based & effective Medication Management, Psychological Evaluations, and Psychotherapy for Adolescents & Adults

Neurodevelopmental Evaluations
A comprehensive ADHD and/or learning disability evaluation is a thorough, evidence-based assessment designed to accurately identify Attention-Deficit/Hyperactivity Disorder (ADHD), learning disorders, and other factors that may be affecting attention, academic performance, and daily functioning. This process goes far beyond brief screening and follows diagnostic standards established by the American Psychiatric Association and criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V). The evaluation includes a detailed semi-structured clinical interview, collateral reports, review of developmental, educational, and psychosocial history, and standardized rating scales to assess attention, executive functioning, and emotional regulation. Formal cognitive, executive functioning, memory, and academic testing is conducted to evaluate intellectual functioning (IQ), learning and achievement skills (such as reading, writing, and math), processing speed, working memory, and other executive functioning abilities. This allows for accurate identification of ADHD, specific learning disorders, or other cognitive and psychological factors that may impact performance. The assessment also includes screening for related conditions such as anxiety, bipolar, depression, trauma, and sleep difficulties, ensuring a comprehensive and accurate understanding of each individual’s strengths and challenges. Following the evaluation, patients receive a detailed feedback session and written report outlining diagnostic findings and personalized recommendations. This report can support treatment planning, medication management, academic or workplace accommodations (such as 504 Plans/IEP or accommodations for standardized testing), and targeted interventions to improve functioning and success. This comprehensive evaluation provides clarity, diagnostic accuracy, and a clear path forward, serving as the foundation for effective, individualized support and long-term success.
Medication Management
Dr. Phan is proud to be one of the pioneer Prescribing Psychologists in Colorado. Medication evaluation management with a Prescribing Psychologist offers a uniquely comprehensive and integrated approach to mental health care. With advanced training in both psychotherapy and clinical psychopharmacology, a Prescribing Psychologist understands how biological, psychological, and behavioral factors work together to influence overall functioning and symptom presentation. This allows medication decisions to be made within the full context of your personal history, therapy progress, and treatment goals. Because therapy and medication management are provided within the same framework, care is more coordinated, efficient, and personalized. Dr. Phan provides comprehensive psychiatric medication evaluation and management as part of an integrated behavioral medicine approach. She specializes in the psychopharmacological treatment of anxiety disorders, obsessive-compulsive disorder (OCD), ADHD, mood and bipolar disorders, and trauma-related conditions for adolescents and adults. Her prescribing approach is thoughtful, evidence-based, and tailored to each individual’s unique neurobiology, symptoms, and treatment goals. Medication management is collaborative and personalized. Dr. Phan works closely with patients to select medications that are both effective and well-tolerated, with careful attention to minimizing side effects and optimizing long-term outcomes. She provides ongoing monitoring, education, and adjustments as needed to ensure treatment remains aligned with each patient’s evolving needs. Her psychopharmacology practice reflects a deep understanding of how medications can support the brain’s capacity for regulation, healing, and resilience. Medication may help reduce symptoms such as persistent anxiety, intrusive thoughts, mood instability, emotional reactivity, sleep disturbance, and difficulty with focus and regulation—creating the stability necessary for meaningful therapeutic work, including CBT, ERP, ACT, and EMDR, to be more effective. Dr. Phan approaches medication as one component of a comprehensive treatment plan. Her goal is not simply symptom reduction, but to help patients achieve lasting stability, improved functioning, and a greater sense of wellbeing. When integrated with psychotherapy and behavioral strategies, medication can be a powerful tool in supporting recovery and restoring balance.

Personal Injury/Medical Evaluations
Personal injury and medicolegal evaluations differ fundamentally from traditional psychotherapy or treatment services. The purpose of these evaluations is to provide an objective, independent assessment that addresses specific legal, medical, or administrative referral questions. As such, Dr. Phan serves as an independent evaluator rather than a treating provider, and no therapeutic relationship is established. Individuals participating in a medicolegal evaluation should understand that information obtained during the assessment is not confidential in the same manner as psychotherapy. Clinical interviews, records reviewed, psychological testing, and professional opinions may be disclosed to the referring attorney, insurance carrier, court, healthcare providers, or other authorized parties involved in the legal matter. Evaluation findings are documented in a written report and may be subject to review, deposition, or courtroom testimony as permitted by law. Dr. Phan has extensive experience conducting comprehensive medicolegal and personal injury psychological evaluations involving complex psychiatric, cognitive, trauma-related, and medical presentations. Drawing upon her strong background in clinical work, psychological assessment, and advanced clinical psychopharmacology, she provides objective, evidence-based opinions regarding psychological injury, emotional distress, functional impairment, and the psychological impact of accidents, injuries, or other traumatic events. A particular strength of Dr. Phan's work is her ability to evaluate nexus and causality. She carefully examines the relationship between an individual's psychological symptoms and the alleged injury or event while considering pre-existing conditions, differential diagnoses, medical history, trauma exposure, and other biopsychosocial factors that may influence functioning. Her evaluations are designed to provide balanced, scientifically grounded opinions regarding causation, aggravation, prognosis, and the impact of psychological symptoms on daily functioning, occupational performance, and quality of life. Each evaluation includes a comprehensive clinical interview, detailed record review, psychological testing when indicated, and thoughtful integration of collateral information. Dr. Phan's reports are clear, well-supported, and clinically defensible, providing attorneys, healthcare providers, insurance carriers, and the courts with objective findings that assist in informed decision-making while maintaining the highest standards of professional ethics and forensic practice.
Anxiety Disorders
Anxiety can affect every aspect of life—from relationships and work to sleep, physical health, and overall wellbeing. At Healing Grove Integrative Behavioral Medicine, Dr. Diem Phan provides comprehensive, evidence-based treatment for the full spectrum of anxiety disorders, including generalized anxiety disorder (GAD), panic disorder, social anxiety, obsessive-compulsive disorder (OCD), specific phobias, health anxiety, and anxiety related to trauma and life stressors. Dr. Phan understands that anxiety is often more than excessive worry. It can involve persistent fear, racing thoughts, physical symptoms, perfectionism, avoidance, difficulty concentrating, irritability, and feeling "stuck" in cycles of fear and uncertainty. She takes the time to understand the underlying biological, psychological, and environmental factors contributing to each individual's anxiety before developing a personalized treatment plan. Treatment is tailored to each patient's unique needs and may include Cognitive Behavioral Therapy (CBT), Exposure and Response Prevention (ERP), Acceptance and Commitment Therapy (ACT), mindfulness-based interventions, and, when appropriate, integrated medication management. Dr. Phan's whole-person approach combines psychotherapy, psychological assessment, and psychopharmacology to help patients reduce anxiety, develop effective coping skills and regain confidence in living a full and meaningful life.

Trauma/PTSD
Trauma can change the way we think, feel, relate to others, and experience the world. Whether the result of a single traumatic event or ongoing experiences such as childhood adversity, abuse, neglect, loss, or interpersonal violence, trauma can have lasting effects on emotional, physical, and psychological wellbeing. At Healing Grove Integrative Behavioral Medicine, Dr. Phan provides compassionate, trauma-informed care to help individuals move beyond survival and begin healing. Dr. Phan specializes in treating Post-Traumatic Stress Disorder (PTSD) and Complex PTSD using evidence-based approaches tailored to each person's unique experiences and goals. Her treatment integrates Eye Movement Desensitization and Reprocessing (EMDR), Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), Ketamine-Assisted Psychotherapy (KAP), mindfulness-based interventions, and, when appropriate, medication management as part of a comprehensive treatment plan. Dr. Phan understands that trauma affects both the mind and body. She works collaboratively with patients to help them process difficult experiences, reduce distressing symptoms, strengthen emotional regulation, and rebuild a sense of safety, confidence, and connection. Her approach emphasizes healing at a pace that feels safe and empowering, while helping patients rediscover resilience, restore hope, and move toward a more meaningful and fulfilling life.
OCD
Living with OCD can be exhausting. Intrusive, unwanted thoughts and the urge to perform rituals or seek reassurance can consume hours of each day, leaving you feeling trapped in a cycle of fear, doubt, and uncertainty. At Healing Grove Integrative Behavioral Medicine, Dr. Diem Phan provides specialized, evidence-based treatment to help individuals break free from OCD and regain confidence in their lives. Dr. Phan has advanced training in Exposure and Response Prevention (ERP), the gold-standard psychological treatment for OCD, and integrates ERP with Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), mindfulness-based interventions, and, when appropriate, medication management. Treatment is individualized to address each person's unique obsessions, compulsions, and avoidance behaviors while helping them build tolerance for uncertainty and reduce the power OCD has over their daily life. Dr. Phan works with individuals experiencing contamination fears, checking behaviors, intrusive thoughts, perfectionism, symmetry concerns, harm OCD, relationship OCD, scrupulosity, and other OCD-related presentations. Her compassionate, collaborative approach helps patients gradually face their fears, reduce compulsive behaviors, and develop the skills needed to live according to their values rather than their anxiety. The goal of treatment is not simply to reduce symptoms, but to restore freedom, confidence, and the ability to fully engage in work, relationships, and the activities that matter most.

Depression
When depression doesn't improve despite therapy, medication, or multiple attempts at treatment, it can be especially discouraging. Dr. Phan has a particular interest in working with individuals experiencing persistent depression and treatment-resistant depression (TRD), including those who feel they have already "tried everything." Rather than simply repeating previous approaches, Dr. Phan takes a fresh look at the clinical picture. She reviews prior treatments and medication trials, patterns of response, possible diagnostic complexities, medical and biological contributors, trauma, sleep, and other factors that may be preventing recovery. Her advanced training in clinical psychopharmacology is especially valuable in complex cases involving multiple medications, incomplete responses, side effects, or uncertainty about the next step in treatment. For patients with treatment-resistant depression, care may involve psychotherapy, thoughtful medication strategies, coordination with medical or psychiatric specialists, and consideration of newer or interventional approaches when appropriate. The focus is on finding a path forward when conventional treatment has not been enough. Most importantly, Dr. Phan recognizes how exhausting it can be to live with depression that keeps returning or simply does not get better. Her work is centered on helping patients regain hope, energy, connection, and a sense of possibility—even after previous treatments have fallen short.
ADHD
ADHD affects much more than attention. It can impact organization, motivation, emotional regulation, time management, relationships, work performance, and self-confidence. Many individuals with ADHD spend years feeling overwhelmed or misunderstood before receiving an accurate diagnosis. At Healing Grove Integrative Behavioral Medicine, Dr. Diem Phan provides comprehensive ADHD evaluations and personalized treatment for children, adolescents, and adults. Dr. Phan takes a thorough, evidence-based approach to ADHD by carefully evaluating attention, executive functioning, emotional health, developmental history, and other factors that may contribute to concentration difficulties. She recognizes that symptoms of anxiety, depression, trauma, sleep disorders, learning differences, and medical conditions can closely resemble or occur alongside ADHD. Through comprehensive assessment and diagnostic clarification, she helps patients gain a clear understanding of their strengths, challenges, and the factors influencing their daily functioning. Treatment is individualized and may include behavioral strategies, executive functioning skills, Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), parent or family education, academic or workplace accommodations, and, when appropriate, integrated medication management. Drawing upon her advanced training in clinical psychopharmacology, Dr. Phan thoughtfully combines psychological and medical approaches to help patients improve focus, organization, emotional regulation, and overall quality of life. Dr. Phan believes that ADHD is not simply a collection of deficits—it is a different way of thinking and experiencing the world. Her goal is to help individuals better understand their unique brain, build upon their strengths, develop practical strategies for success, and gain the confidence to thrive at school, work, home, and in their relationships.

Immigration Evaluations
Dr. Phan provides compassionate, culturally responsive psychological evaluations to support individuals and families navigating the U.S. immigration process. With her significant experience conducting these specialized immigration evaluations, she understands the significant emotional, psychological, and legal complexities that often accompany immigration cases. Her evaluations are comprehensive, objective, and grounded in current clinical and forensic standards. Dr. Phan conducts evaluations for a variety of immigration matters, including Hardship Waivers (I-601/I-601A), VAWA petitions, asylum cases, and N-648 Medical Disability Waivers for Naturalization. These evaluations carefully assess the psychological impact of trauma, persecution, abuse, family separation, medical conditions, and other life experiences that may be relevant to an individual's immigration case. Each evaluation includes a thorough clinical interview, review of supporting documentation, psychological assessment when appropriate, and a detailed report that clearly explains diagnostic findings, functional impairment, and the relationship between psychological symptoms and the legal questions being addressed. Dr. Phan has particular expertise in establishing nexus and causality, thoughtfully connecting an individual's mental health symptoms to traumatic experiences or other relevant factors through evidence-based clinical reasoning. Above all, Dr. Phan recognizes that every immigration story is deeply personal. She is committed to providing a respectful, supportive, and trauma-informed evaluation process while producing high-quality, objective reports that can assist attorneys, adjudicators, and immigration officials in understanding the psychological impact of an individual's experiences.
Veterans/Military Evaluations
Dr. Phan is honored to serve veterans, active-duty military personnel, federal employees, and individuals seeking employment-related psychological evaluations. She has extensive experience conducting comprehensive psychological assessments for military readiness, occupational fitness, security and employment clearances, disability evaluations, and return-to-duty determinations. Her evaluations are objective, thorough, and tailored to address the specific clinical and occupational requirements of each referral. With a strong understanding of military culture and the unique demands placed on service members and public safety professionals, Dr. Phan evaluates concerns related to PTSD, trauma, anxiety, depression, ADHD, substance use, sleep disturbances, resilience, cognitive functioning, and overall psychological readiness. She also conducts pre-employment, fitness-for-duty, pre-PCS (Permanent Change of Station), and other specialized evaluations that help determine an individual's ability to safely and effectively perform the essential functions of their role. Drawing upon her expertise in psychological assessment and clinical psychopharmacology, Dr. Phan provides clear, evidence-based opinions that integrate clinical findings with occupational and functional considerations.

Ketamine-Assisted Psychotherapy
Ketamine-Assisted Psychotherapy (KAP) combines specialized psychotherapy with medically-supervised ketamine treatment as part of a carefully selected and individualized treatment plan. At Healing Grove Integrative Behavioral Medicine, Dr. Phan brings her extensive background in trauma treatment, psychotherapy, and clinical psychopharmacology to helping patients explore whether ketamine-assisted treatment may be appropriate for their needs. Dr. Phan has completed specialized Ketamine-Assisted Psychotherapy training through Elemental Psychedelics, complementing her doctoral training as a Psychologist and advanced Post-Doctoral education and fellowship in clinical psychopharmacology. Her approach emphasizes careful assessment, preparation, therapeutic support, and integration—the process of helping patients understand and meaningfully incorporate insights and experiences that may emerge during treatment. KAP may be considered within a broader treatment plan for appropriately selected adults experiencing complex or persistent mental health concerns, particularly when traditional approaches have not provided sufficient improvement. Treatment decisions are individualized and include consideration of psychiatric history, medical health, current medications, previous treatment response, potential risks, and alternative treatment options. At Healing Grove, ketamine is never viewed as a stand-alone solution. The emphasis is on combining appropriate medical care with the depth of psychotherapy to support meaningful and sustainable psychological change.
Bipolar Disorders
Bipolar disorder can be complex and is often misunderstood or misdiagnosed. Changes in mood, energy, sleep, motivation, impulsivity, and concentration can overlap with conditions such as ADHD, anxiety, trauma, and depression. Dr. Phan has particular expertise in the assessment and treatment of bipolar spectrum disorders, with an emphasis on careful diagnostic clarification and individualized, long-term care. Drawing upon her training as a Psychologist and her advanced education in clinical psychopharmacology, Dr. Phan approaches bipolar disorder from both psychological and biological perspectives. Treatment may integrate psychotherapy, medication management, sleep and lifestyle interventions, education about mood patterns and early warning signs, and collaboration with other medical providers when appropriate. Particular attention is given to medication history, treatment response, side effects, medical conditions, and factors that may contribute to mood instability. Dr. Phan believes successful treatment is about more than controlling episodes. She works collaboratively with patients to help them better understand their mood patterns, recognize triggers, strengthen emotional regulation, improve relationships and daily functioning, and develop strategies for maintaining stability over time. Her goal is to help individuals with bipolar disorder experience greater stability, confidence, and quality of life while still honoring the person beyond the diagnosis.
