Lillian Cole, MD
I emphasize a holistic, patient-centered approach that integrates evidence-based medicine, psychotherapeutic techniques, lifestyle interventions, and psychoeducation. I believe that listening, collaboration, and compassion are essential to guiding patients toward recovery. My practice primarily focuses on psychiatric medication management, and I have extensive experience treating mood disorders, anxiety, trauma-related disorders, and substance use disorders. When additional therapy is necessary for the best outcome, I may recommend integrating a therapist into the treatment plan.
I am a board-certified adult psychiatrist. I completed my undergraduate education at the University of North Carolina Wilmington and went on to earn both a master's in biomedical sciences and a medical degree from Texas Tech University. I completed my psychiatry residency training at the University of Texas Southwestern Medical Center, where I gained experience working with a diverse range of patient populations across different ethnic, socioeconomic, and clinical backgrounds.
Patients can expect a thorough and compassionate initial evaluation, where I take the time to understand their symptoms, medical history, and treatment goals. I focus on fostering a strong doctor-patient relationship and collaborate with each patient to create a personalized treatment plan that may include medication management, therapy, and lifestyle interventions. If additional therapy is indicated, I will coordinate with other providers to ensure comprehensive care tailored to the patient's needs.

Lisa Ekeanyanwu, MD
My practice is centered on pharmacotherapy, which I integrate with supportive therapy, cognitive behavioral therapy (CBT), and psychodynamic therapy to provide comprehensive psychiatric care. I take a collaborative and individualized approach, tailoring treatment to meet each patient's unique goals and improve their overall quality of life. I have a special interest in cultural and micro-cultural influences on mental health and strive to provide culturally competent care that respects each patient's life experiences and values. When I believe additional therapy may be beneficial, I may recommend incorporating a therapist into the care team.
I am a board-eligible psychiatrist who completed my psychiatry residency training at Stanford University. I have gained experience in a wide range of clinical environments, including inpatient and outpatient care, community mental health settings, emergency rooms, telehealth services, and international clinical fieldwork.
During a first visit, patients can expect a thorough evaluation in which I carefully assess their symptoms, medical history, and personal treatment goals. I foster a collaborative and patient-centered environment, ensuring that each treatment plan aligns with the patient's individual needs. I provide medication management along with therapeutic support and, when appropriate, may recommend additional therapy to optimize outcomes. My approach prioritizes safe, effective, and culturally sensitive care that evolves to support patients throughout different stages of their lives.

Lisa Oliveri-Naidu, MD
I have a strong interest in treating a broad range of psychiatric disorders, including depression, anxiety, posttraumatic stress disorder, and substance use disorders. I am approachable, open-minded, and collaborative in my diagnostic interviews and treatment planning. I believe that a strong doctor-patient relationship with a thorough understanding of a patient's condition and concerns is key to effective treatment.
I am a double board-certified psychiatrist in Psychiatry and Forensic Psychiatry. I completed my undergraduate training at the University of Florida, followed by medical school at the Charles E. Schmidt College of Medicine at Florida Atlantic University. I completed both my residency in Psychiatry and fellowship in Forensic Psychiatry at the University of Miami/Jackson Memorial Hospital. Since graduating from fellowship, I have held an academic appointment at the University of Miami, teaching medical students, residents, and fellows, and serving as the Miami Veterans Healthcare System Site Director for the University of Miami Psychiatry residency and fellowship programs. Additionally, I have served as the Medical Director of the inpatient psychiatry unit and subsequently as the Assistant Chief of Psychiatry for the Miami VA Healthcare System. I have extensive experience in treating adults with severe psychiatric illnesses in the inpatient setting.

Mallory Jacobs, MD
I am board-certified in Adult Psychiatry by the American Board of Psychiatry and Neurology. I specialize in medication management for adult patients across a range of psychiatric conditions, with a focus on treating depression, anxiety, bipolar disorders, and ADHD. I employ a therapeutic approach to medication management, incorporating supportive and psychodynamic psychotherapies into my sessions, and I select psychopharmacological treatments and therapies tailored to each patient's individual needs and symptoms. I take great pleasure in connecting with patients via telemedicine, focusing on meeting them where they are in their mental health journey and supporting their needs and goals.
I earned my Bachelor of Science in Science and Business from the University of Notre Dame and graduated from medical school at the University of Mississippi, where I was honored with membership in the Gold Humanism Honor Society for my exceptional clinical skills, interpersonal abilities, and dedication to patient care. I then returned to Texas to follow my passion for mental health, completing my residency in Psychiatry at the University of Texas Southwestern Medical Center. I developed a strong enthusiasm for enhancing mental health care within communities and completed a fellowship in Community Psychiatry through the UT Southwestern Altshuler Center for Education and Research in the Dallas-Fort Worth area.
Over the years, I have worked with major community mental health organizations across Texas and have recently focused on leveraging telemedicine to coordinate mental health support with primary care providers. Throughout my career, I have been committed to psychiatric research, educational initiatives, and organizational efforts to advance mental health care education and patient care in communities. I am an active member and leader in several medical and psychiatric organizations.

Manuel Guillen, MD
I am committed to providing thoughtful, evidence-based mental health care in a supportive and respectful environment. I believe psychiatric care is most effective when patients feel heard, well-informed, and actively involved in treatment decisions, creating a collaborative relationship that supports lasting improvement. I take a collaborative and thorough approach to care, spending time understanding each patient's history, daily life, strengths, and current challenges. I emphasize individualized treatment that includes careful diagnosis, medication management when appropriate, and practical strategies that support long-term mental health. Treatment plans are developed together with patients to ensure they are medically sound, realistic, and sustainable, with the goal of helping individuals achieve stability, resilience, and improved quality of life. Patients can expect appointments that are attentive, calm, and focused on meaningful progress.
I have a longstanding interest in both medicine and the humanities, which naturally led me to psychiatry as a field that integrates both disciplines. I have worked across a wide range of psychiatric settings, including inpatient, outpatient, consultation-liaison, residential, and emergency psychiatry. I earned my Bachelor of Arts from The University of Texas at Austin, received my medical degree from Ross University School of Medicine, and completed my Psychiatry residency at Texas Tech University Health Sciences Center at El Paso. I am a Diplomate of the American Board of Psychiatry and Neurology and a Fellow of the American Psychiatric Association.

Maria Orejarena Serrano, MD
I incorporate different therapy modalities and evidence-based treatments, tailored to each person's needs. I enjoy applying my knowledge in neuroscience and pharmacology into my clinical practice and believe a combination of medication and psychotherapy yields the best treatment outcomes. My ultimate goal is to help patients feel their best and accomplish their own goals by developing tools to navigate internal or external obstacles that are part of life.
I am board certified by the American Board of Psychiatry and Neurology. I completed my residency at Yale University and the University of Texas Houston. I have done extensive research on psychiatry during my PhD in Neuropsychopharmacology and a Master's in Neuroscience. I am originally from Colombia, where I earned my medical degree from Universidad Industrial de Santander. I pursued a Master's in Neuroscience at the University of Barcelona and a PhD in Neuropharmacology at the Universidad Pompeu Fabra in Barcelona, Spain. My PhD thesis was honored summa cum laude. I completed a postdoctoral fellowship training at the Institut de Neurobiologie de la Mediterranee in Marseille, France. I am the author of multiple peer-reviewed publications and have presented my research at national and international meetings. Over the years, I have worked in a variety of settings including outpatient clinics, acute care, and psychiatric hospitals as an Assistant Professor of Psychiatry at the University of Texas Health Sciences Center.
I am bilingual in Spanish and English.

Mark Varela,MD
I focus primarily on medication management, often accompanied by brief cognitive, motivational, or supportive therapy. I may request that you also meet with a therapist regularly for your benefit. I treat young adults and adults with a wide variety of mental health concerns, including ADHD, mood disorders, anxiety, OCD, and PTSD.
I am a board-certified psychiatrist joining Talkiatry directly out of residency. I received my medical degree and completed my general psychiatric residency training at Texas Tech University Health Sciences Center in West Texas.

Marsha Wheatley, MD
What has motivated me over the course of my career as a caregiver? I am a native Houstonian who grew up in a working-class community. Through curiosity and hard work, I was able to attend a university that included people of vastly different life experiences. I was molded by both communities to appreciate the commonalities of humanity. That broad exposure extended my empathetic spectrum to grasp the needs of the American diaspora.
I use a biopsychosocial approach to evaluate the patient. I gather patient history with a mindset that considers the neuroscience that chemically shapes mood, thoughts, and behavior. I am able to uncover factors that can inhibit psychological growth and development. I have experience in seeing how the social conditions of the œthen can influence the resiliency of the œnow. I appreciate, and am proficient in, advances in technology, but prioritize the analog relationship between doctor and patient.
Meeting people where they are. It is an old trope, but describes how one allows a patient to set the path forward. An open-ended interview is conducted with an open mind towards resolution. When being evaluated and treated by me, a patient can expect to be met in a cordial but professional manner. Treatments are discussed and considered based on the mental state of the patient and the clinical efficacy and scientific evidence of benefit. The patient is invited to ask questions and consider whether they wish to pursue the suggested treatment plan.

Matthew Hamilton, MD

Dr. Hamilton’s practice focuses on medication management. Typically, he offers this in conjunction with supportive or emotionally focused therapy in 30-minute follow-up visits.

your care team to provide the best outcome.
After completing his undergraduate education at the University of Texas at Austin he completed his medical education at Texas Tech University Health and Sciences Center, Paul L. Foster School of Medicine, and recently completed his residency training at the University of Texas Medical Branch in Galveston.
Dr. Hamilton has a diversity of experience in practicing general psychiatry treating adults of all age ranges.

Matthew Kelly, MD
I am a board-eligible psychiatrist specializing in adult psychiatry. I provide compassionate, comprehensive care for adults facing a wide range of mental health conditions, including depression, anxiety, PTSD, OCD, ADHD, and bipolar disorder. I emphasize a holistic, evidence-based approach that incorporates medication management, supportive therapy, and lifestyle interventions targeting nutrition, exercise, sleep hygiene, and stress management to improve an individual's wellbeing.
I take the time to understand each patient's unique needs and work collaboratively to develop personalized treatment plans that are non-judgmental, empowering, and focused on overall well-being. I believe an essential aspect of the therapeutic relationship is an individual's ability to make informed choices. I actively involve individuals in their treatment and use clear communication to help patients understand their care so they can focus on their journey of healing and recovery.
I completed my undergraduate studies at the University of Houston before attending McGovern Medical School, where I completed both my medical degree and my psychiatric residency.

Matthew Koller, MD
Most of my work as a psychiatrist is with adults navigating PTSD, OCD, and the shifts that come with becoming a parent, including postpartum depression. I also spend time with people managing more complex patterns, like personality disorders, bipolar disorder, and anxiety that has quietly reshaped their daily lives. I trained in general adult psychiatry at Baylor College of Medicine, where I served as Chief Resident of Education in my final year, and I bring an analytical, problem-solving mindset to sorting out what's actually driving a person's symptoms.
I don't think good treatment can start until I understand someone fully, so the first visit is a thorough evaluation where I take my time with your history, your symptoms, and what you're actually hoping to change. Medication management is the foundation of what I do, but it's one piece of the picture, not the whole plan. Depending on what you need, I'll fold in supportive therapy or recommend adding a therapist so the care around you is well-rounded. I try to be transparent about my reasoning and to build decisions with you rather than hand them down, and I tend to look for the strengths already there to work from.
I especially find common ground with parents and caregivers trying to hold their own health steady while looking after everyone else. The first step is really just a conversation, and we sort out the direction together once I understand where you're starting from.

Matthew Thompson, MD
Dr. Matthew Thompson earned his medical degree from the University of Texas Medical Branch at Galveston, completed his psychiatry residency at Baylor College of Medicine, and completed fellowships in geriatric psychiatry at Mount Sinai School of Medicine and addiction medicine at Memorial Hermann Prevention and Recovery Center. He has extensive experience in general, geriatric, and addiction psychiatry in both inpatient and outpatient settings, including telehealth.
Dr. Thompson values open communication and works with patients to set clear treatment goals. He creates a warm, supportive environment where patients feel heard and respected, emphasizing that medication, when needed, is usually only one part of improving symptoms and quality of life.
Dr. Thompson reviews each patient's full history to develop an accurate diagnosis and individualized treatment plan rather than relying on a checklist of symptoms.

Mental health care in San Antonio
Access to psychiatric care is stretched across Texas. The state has 393 federally designated mental health professional shortage areas, and only about 32.2% of its need for mental health practitioners is met. An estimated 606 more psychiatrists would be needed to remove those shortage designations, according to KFF.

Can I just go straight to a psychiatrist?

What is the 3 month rule in mental health?

There is no single official "three-month rule" in psychiatry. The phrase usually points to the fact that some diagnoses depend on how long symptoms last. Clinicians often look at how many weeks or months certain symptoms have been present before naming a condition. A psychiatrist can walk you through what the timing means for your situation.
How much does a psychiatrist cost in Texas?
