Peter McGowan, MD

Dr. McGowan is a board-certified adult psychiatrist with over 14 years of experience, during which time he primarily treated active-duty US Navy sailors, their family members, and military retirees in the outpatient setting. His practice focuses on medication management in addition to supportive and cognitive-behavioral therapy in 30-minute follow-up visits. He is a strong advocate of multiple treatment modalities and, in certain situations, may suggest that therapy and/or regular physical exercise be included in your treatment plan to provide the best outcome. He received his B.S. in Physics from the United States Naval Academy. After serving as an Intelligence Officer in the Navy for eight years, he transitioned to medicine and earned his medical degree from the Uniformed Services University of the Health Sciences in Bethesda, MD. After completing an intern year in Family Medicine, Dr. McGowan completed residency training in Psychiatry at Naval Medical Center Portsmouth, VA, where he remained on staff for the next ten years and was primarily involved in resident training and education. He held academic appointments at the Uniformed Services University and Eastern Virginia Medical School and served as the Psychiatry Residency Program Director for six years. He served his final four years in uniform running the behavioral health department at Naval Air Station Whidbey Island, WA. He recently retired from the Navy after a 30-year career. Dr. McGowan has extensive experience in outpatient psychiatric care. In addition to the full spectrum of mood and anxiety disorders, he has treated a very large number of patients with PTSD stemming from combat, natural disasters, and sexual trauma. He believes that, like his service to the country, working alongside others in their journey to better mental health is an incredible privilege.

Michael Manasterski, MD

Staff Psychiatrist

Dr. Michael Manasterski is a board certified general psychiatrist. Before joining Talkiatry, he had the honor of working for the Department of Veterans Affairs in both outpatient and residential settings, and gained experience in improving quality of life for veterans with a wide range of troublesome to downright disabling psychiatric conditions, including severe anxiety and mood disorders, psychosis, obsessive-compulsive disorder, developmental disorders including autism spectrum and attention-deficit disorders, and post-traumatic stress disorder. These disorders have almost certainly been with us for all of recorded human history, but within the last few generations, our understanding of and ability to treat these conditions has grown by leaps and bounds.

Dr. Manasterski trained at the University of South Florida, earning his Bachelor of Science in Biology, and completing medical school and residency at the Morsani College of Medicine in Tampa, Florida. During his time in training and at the VA, his passion for teaching, both medical trainees and patients, found a productive outlet. He looks forward to bringing that experience forward to serve the broader population in these unprecedented times.

Dr. Manasterski’s practice is centered on evidence-based medication management, expertly tailored to each unique individual, informed by the best available research, using a multidisciplinary approach where appropriate to achieve the best possible outcome. He offers motivational interviewing and supportive psychotherapy, and can collaborate with a therapist on your care team when more specialized treatment is needed on your journey to wellness.

David Sahadevan, MD

Staff Psychiatrist

Dr. Sahadevan took an adventurous path to Talkiatry. After perhaps thinking a little too hard about Intro to Philosophy in college - "the unexamined life is not worth living” - he first used his chemistry degree to work in pharmaceutical research. He changed course, working in computer network engineering, before deciding to find a more meaningful path. He worked as an EMT, then earned a Master's in Physiology before finally landing in medical school at Ohio State. Finding a surprising interest in psychiatry, he stayed at Ohio State for residency, and then a fellowship in forensic psychiatry. He is board-certified in both Psychiatry and Forensic Psychiatry. He previously worked as a forensic psychiatrist and evaluator at Ohio's maximum-security state psychiatric facility, as an attending psychiatrist running an inpatient unit for violent or dangerous patients, performing court-ordered evaluations, writing reports, and testifying when necessary. Dr. Sahadevan has also worked as a consultation-liaison psychiatrist, performing psychiatric consults at several general hospitals in Central Ohio's largest hospital system. He found great enjoyment in teaching successive generations of residents and medical students, serving as an adjunct faculty member at Ohio State, Ohio University, Wright State, and OhioHealth Riverside Methodist Hospital. He is excited for the next chapter of his journey, exploring another area of psychiatry at Talkiatry!
