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!

Dr. Ernesto Gonzalez is a board certified adult psychiatrist. He completed his undergraduate training at Yale University and received his medical degree from the University of Pennsylvania School of Medicine. He completed his residency training at the Cambridge Health Alliance/Harvard Medical School Adult Psychiatry Training Program. Dr. Gonzalez prefers a holistic approach that takes the time to know the whole patient, incorporating biological, psychological, social, and cultural perspectives in crafting a comprehensive, individualized, treatment plan. He practices medication management combined with supportive therapy, typically delivered within 30 minute sessions. Elements of psychodynamic, dialectical behavior and cognitive-behavioral therapy will also be incorporated into sessions based on a patient's individual needs. If additional therapy is needed, Dr. Gonzalez will recommend the addition of an individual therapist to the patient's treatment team. Having dedicated his career to adult outpatient psychiatry, Dr. Gonzalez has worked with patients from a wide range of ages, cultures, ethnicities, and social settings across the New York City area.
