What People Say About Dr. John Nicasio, DO
RecentHighestLowestMost Helpful

Didn't give me the results of a test for weeks- even though I was calling the office every once in a while to check. After discussing my financial needs (I'm a student), they called me, gave me the results of my test, didn't schedule an appointment and I never heard from them again. I had gone three times to this office to figure out why my hormones were off. Dr. Nicasio needed me to explain what an ectopic pregnancy was which was weird...but he also didn't know how to use his own software, so many of my symptoms never made it to my original paperwork. I finally called my PCP to refer me elsewhere.

Dr. Nicasio treated me like a whole person and was willing to work collaboratively with me in my treatment plan. He listened to everything I had to say, was very thorough in reviewing my symptoms/ history, and he ran all of the tests that my GP wouldn't do. He also asked me what I wanted to do, what treatment I wanted, and let me ask questions. He looked at the whole picture: my financial needs, my lifestyle, my history, etc. The receptionist is also super nice and helpful. Go see Dr. Nicasio!
