Dr. Tillberg practices patient-centered and trauma-informed care, valuing patient autonomy and collaborative decision-making, acknowledging the burden many people carry from intersecting oppressions. She believes therapy is important � often equally important as medication, or more � and will work together with you to make a realistic treatment plan that will fit into your life.

Dr. Tillberg looks forward to meeting you.

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!
