This psychiatrist is very knowledgeable and kind and she meets me where I’m at. She really tailors treatment plans to you as an individual and works with team members together when she’s able to. She does her best to keep up to date on everything and is a willing participant to work with my medical and mental health team! What I appreciate the most about Dr. Hristea is her dedication, commitment and willingness to help me get to a better place medically and psychiatrically. I appreciate everything she has done for me. Thank you Dr. Hristea!
