Dr. Callahan is a life saver. I mean that in every sense. She has not only helped my husband get on the right medication and right dosages, but she continues to monitor him and asks all the right questions to keep him in a stable and thriving state of mind. We searched for over a year for a doctor like her. We are thrilled she was able to take my husband on as a patient. She is by far the best we have ever had. Thank you Dr. Callahan for caring about people and your dedication to mental health

Melissa is a professional in her field. She answers questions thoroughly, precise, and ensures you are comfortable with your treatment and options. I've been transformed for the better, and live a much healthier and happier life since becoming a patient here. I can't express how much I have gained. Staff is nice, wait times are not long, and the environment is clean. I can't see how it could be better.
