What People Say About Dr. Leonard Lantz, MD
RecentHighestLowestMost Helpful
I would highly recommend Dr. Leonard Lantz. I am a 20s male and I have struggled with Major Depressive Disorder, Bipolar I Disorder, and frequent anxiety. Dr. Lantz takes his time to get to know you and is not a doctor who fills a quick prescription and sends you on your why, he really does want to help and get to the root of the problem. Medications he may recommend and/or prescribe is something the patient has a say in and works with their lifestyle decisions. 95/100.

Dr. Lance has been an incredible Physician to our teenage son with Schizophrenia. He has seen most of the child psychiatrists in our area and Dr. lance didn't make uninformed diagnosis, nor did he pass us on to someone else or simply try to just treat symptoms. He is thorough, listens, and follows through. I'd recommend him to any family struggling with the lack of Mental health providers and resources in Montana.
