Matthew Koller, MD

I have over 20 years in healthcare, beginning as a caregiver, CNA, LPN, and RN before becoming an FNP and later a PMHNP. I earned my ADN from Gogebic Community College, BSN and MSN/FNP from Herzing University, and post-master’s PMHNP Certificate from the University of Cincinnati. I have worked in home health, primary care, urgent care/ER, and outpatient psychiatry, and have served as Psychiatric Director for HOPS and Clinical Adjunct Faculty for Concordia University.

I believe rapport is essential to high-quality care. I strive to create a warm, caring environment where you feel comfortable, heard, and supported. I value open communication and take time to learn your unique story.

I begin with a thorough review of your medical and psychiatric history, then work with you to identify your goals and create an individualized plan. I view treatment as a partnership and want you to feel heard and involved. I use supportive psychotherapy, education, and resources such as books or workbooks, and encourage therapy when helpful. I explain treatment options and view medication as one “tool in the toolbox” while working toward the root of concerns and empowering you to heal and reach your goals.

Trevor Gee, APRN, PMHNP-BC, brings over a decade of healthcare experience and earned his degree from the University of Nevada, Las Vegas. He has worked with individuals experiencing depression, anxiety, bipolar disorder, psychotic disorders, personality disorders, and ADHD. Trevor is passionate about individualized, evidence-based care and has extensive training in FDA-approved and off-label TMS protocols.

Trevor believes mental health care should never take a “cookie-cutter” approach. He values open communication, collaboration, and patient-centered care while creating a supportive environment where patients feel heard and respected. His holistic approach may include medication management, psychotherapeutic techniques, lifestyle changes, nutritional support, and other evidence-based treatments focused on long-term healing and well-being.

Trevor begins by understanding each patient’s history, symptoms, concerns, and goals. He collaborates with patients to create personalized treatment plans tailored to their needs and preferences. Depending on the individual, care may include medication management, supportive therapy, TMS therapy, genetic testing, and lifestyle-focused interventions to support lasting progress and improved quality of life.

I am dual-certified as a Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-C). My background in family practice and psychiatry helps me understand how emotional health, physical health, relationships, and life experiences are connected. I have cared for people with anxiety, depression, ADHD, mood disorders, trauma-related symptoms, and substance use.

I understand that reaching out for mental health care can feel vulnerable. My goal is to create a warm, respectful space where you can speak openly and feel heard. I do not believe in one-size-fits-all treatment. We will work together to determine what feels realistic, meaningful, and helpful for your life. Medication can be an important tool, but it is not the only one. When appropriate, visits may include supportive therapy, coping skills, and exploration of sleep, stress, relationships, physical health, and routines.

Our first visit is an opportunity for me to hear your story, understand your concerns, and learn what you hope will change. We will explore your symptoms, history, physical health, medications, previous treatments, sleep, stressors, strengths, and what has or has not helped. From there, we will create a plan together. Follow-ups focus on progress, response to treatment, and adjusting the plan as your needs, goals, and circumstances change.

I am a board-certified adult psychiatrist with over 30 years of experience. I earned my medical degree from the University of Texas Health Sciences Center in Houston and completed residency training at Texas & M-Scott & White in Temple. I am happily married, with two wonderful adult sons and a lovely daughter-in-law. My hobbies are reading, sports, music, and history.

Psychiatry has always been more than just a job, as I chose this calling at the age of 14 after growing up with a severely mentally-ill mother. This experience has shaped my style as a provider - seeing each person as more than just another "patient." I will empathetically listen to you in a non-judgemental fashion to understand your detailed history, and will work with you to create an individualized treatment plan.

I use pharmacology and supportive therapy, as well as mindfulness and motivational interviewing. I respond quickly to your inquiries and pride myself on keeping up to date with the latest in psychiatry.

I have practiced clinical Psychiatry, predominantly in the outpatient setting, with over a decade of post-graduate inpatient experience, since completing my psychiatric residency at the University of Connecticut Health Sciences Center in 2008. Prior, I received a bachelor’s degree in Psychology from the University of Texas at Austin in 1999, graduating with high honors, and a medical degree from the University of Texas Medical Branch in Galveston in 2004. I have been certified by the American Board of Psychiatry and Neurology since 2009.

I am a collaborative physician, interested in the full picture of a patient’s life and inviting questions and discussion about what is and is not pathology, and which treatment plans fit an individual’s goals and lifestyle. I am often praised as “the only one who ever explains things,” and have won awards as the best mental health provider in my region twice in recent years.

With a substantial background in psychotherapeutic training, I work to minimize and justify the role of psychotropic medication in my patients’ lives, regularly reviewing propriety and necessity. Front and center is always quality of life, not impersonal diagnostic categories. I strive to help my patients “meet themselves where they are” as individuals, with an emphasis on resilience. My ultimate goal is to no longer be necessary.

I earned my medical degree from Universidad Central del Caribe in Puerto Rico and completed my psychiatry residency at John Peter Smith Hospital in Fort Worth, Texas, with extensive training in community outpatient, inpatient, and emergency psychiatry settings. I am fluent in English and Spanish.

I approach care with compassion and value creating a collaborative environment with open communication and patient-centered treatment goals. My practice integrates medication management with supportive psychotherapy, while considering lifestyle modifications.

I begin with a comprehensive evaluation of your history, concerns, and treatment goals using evidence-based approaches. Follow-up appointments focus on monitoring progress and adapting care as needed.

I graduated from Southern Methodist University with a BS in Health and Society. I completed medical school at the University of Texas Medical Branch and Psychiatry Residency Training at FAU Schmidt College of Medicine. I am psychodynamically trained and trained in Cognitive Behavioral Therapy for Insomnia. My experience spans inpatient, emergency, outpatient and Veterans Affairs psychiatry, including PTSD and substance abuse.

I am passionate about mental health, with a focus not only on treating illness but also on promoting overall well-being. I offer a warm, friendly, non-judgmental approach and seek to understand the whole person, including their story and struggles. I do not believe I alone can change a patient, but can help the patient help him/herself. I offer supportive therapy, CBT-style approaches, and interpersonal communication skills development based on patient needs. I want patients to feel comfortable, safe, and able to speak freely.

I start with a self-introduction and spend a few minutes listening before discussing the chief complaint. I use open-ended questions to understand family, medical, social, and psychiatric history. I consider organic causes and request baseline labs. By the first or second session, I aim to have a big picture that we fill in over time. I develop a dynamic treatment plan around the patient-stated goal and check in to course-correct.

I am a board-eligible Psychiatrist specializing in general adult psychiatry, with a focus on depression, anxiety, bipolar disorder, OCD, and ADHD in adults ages 18-64.

Outside of work, I enjoy volleyball, rock climbing, soccer, and playing piano.

I take a holistic, collaborative approach and work closely with patients to address their concerns and priorities. I combine medication management with supportive therapy and lifestyle interventions. I value long-term relationships, continuity of care, and building trusting, supportive connections with my patients.

I am a double board-certified adult and child/adolescent psychiatrist who believes the person sitting in front of me is more than a diagnosis. I believe in individualized, patient-centered care and in meeting people where they are. My approach is collaborative, with trust, transparency, and truly getting to know each person at the center.

I believe patients should have autonomy in decisions about their health. My role is to listen, educate, provide support, and help patients make informed decisions consistent with their goals and values. I do not simply tell someone what medication to take; we develop the treatment plan together.

My first appointment is often less about checking boxes and more about, “Let me get to know you.” I listen to the patient’s story and strive to understand the whole person. My practice combines evidence-based medication management with supportive psychotherapy and, when appropriate, CBT, mindfulness, emotional regulation, behavioral activation, and other therapeutic tools. Medication may be important, but lifestyle changes and therapy are also part of the larger picture.

Dr. Schlager begins by listening openly to each patient's story, including any past experiences of trauma that may be contributing to their current distress. Interviews progress from conversational overview to more specific and problem focused discussion. Diagnosis and treatment response are often best determined by what patients report rather than by conventional blood testing or imaging. As such, he takes care at every stage to help patients articulate their condition and specific concerns, to recognize their meaning in a psychological and social context, and to regularly update goals of care.
