His background includes medical training at the University of Utah, leadership as Student Body President, and psychiatric residency at the University of Texas, where he served as Inpatient Chief Resident and received awards for both clinical excellence and medical education. he brings that same commitment and curiosity to his work with patients. Outside of clinical care, he is deeply interested in narrative medicine—the way our personal stories shape our mental health—and uses that lens to help patients find meaning, clarity, and strength in their own journeys.

As a psychiatrist, Dr. Taylor Brady approach is rooted in compassion, collaboration, and respect for your unique story. He views mental health treatment as a partnership—one where psychotherapy and medication can work together to support your growth and healing. His goal is to help you uncover the patterns and behaviors that may be holding you back, and empower you to make meaningful, sustainable change. He encourages patients to take ownership of their mental health, and he is here to provide the tools, guidance, and support you need along the way.

We’ll begin by taking the time to understand your story, your goals, and what brings you to treatment. The first few sessions focus on building trust and identifying the areas where you’d like to see change. From there, we’ll collaboratively develop a treatment plan that may include psychotherapy, medication, or both—always tailored to your needs. He draws from multiple therapeutic approaches, including Cognitive Behavioral Therapy (CBT), Cognitive Processing Therapy (CPT), and Psychodynamic Psychotherapy, to provide care that fits you, not the other way around. Throughout our work, he'll support you in developing insight, resilience, and confidence in managing your mental health.

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!
