Thomas A. Koroscil's Online Review Report Card

I love Dr Koroscil. He’s on time, kind, professional, thorough, and most importantly he's a really good endocrinologist.

He was rude and treated me like I was dumb. His medical assistant worked part time and didn't return messages in a timely manner, if at all.

The Best Dr I've EVER been a patient and Medical offices are usually one step above a visit to the dentist, (besides the practitioner), of course. I'm complicated and take better than fair care of myself, yet, there is allllways something. This Dr and his Staff are Thee Best. I'm from Hollywood, CA and I will take Dayton+Columbus Ohio Dr's over anyone in CA. With Insurance or out of pocket, I'm sooooThankful for this Dr and his Staff!)👍💯👍

Very peculiar man. My wife went to him, so I decided to give him a try. He told my wife that her regular doctor was doing everything wrong. Then he told her that most doctors do not know how to treat thyroid conditions properly, only he and a few others like him can. When I got there, he very directly focused in on my testosterone treatment, while ignoring what I went to him for. I get my testosterone treatment from my Urologist. (where most of us go for Testosterone). I did not go to DR. Koroscil for testosterone. That was doing fine. He kept saying that the dose was all wrong, the frequency was all wrong, etc. etc. Again, the story is that other doctors have it all wrong, and only he can properly treat people. My urologist and primary care guy have been carefully testing, evaluating, and treating my low testosterone with very close attention for over 20 years. Dr. Koroscil knows almost nothing about my case and has just met me, but is accusing all the other doctors of misconduct, when he does not even know what they have observed and what treatments they have tried. It was very weird. He seems to have an obsession with thinking only he can do things right. He seems to start his encounters with a hunt for something he can use to prove to you that he is better than everyone else. After two visits I still could not get him to address the problem I went to him for. Eventually I gave up and thanked him for his time and left. (In fact he should have thanked me for my time he wasted most of two days of my life.)

Wonderful, caring, responsive doctor.

Excellent doctor has been doctor to presidents of the USA. I am so glad to have been a patient for 3 years. Super person and doctor.

I've been seeing Dr koroscil since 2015. He's always treated me well, along with his staff. He was on top of my thyroid issues.

I’ve been a patient of his for now 3 years. I receive a phone call 1 week before my appointment to say he can’t see you because he’s going outta town. Did he not know he was going when I made this back in March?! I work and can only schedule for when I’m off work. I’ve had appts in the past like this, cancelled outta nowhere. His staff is very unprofessional, when I told her I could only be seen on Thurs/Fri her attitude is like oh well, he can only see pts now on M,T,W. Bull, my cancelled appt was a Thursday. But you guys inconvenienced me, I gotta find another DR quick

Doctor and staff very professional

I have known and seen Dr Koroscil for almost 20 years and I totally disagree. He is more aggressive in his treament of diabetes and thyroid diseases. He even holds a tighter line on medication issues. When I was out of town and had received bad insulin, he worked with the TN pharmacy to get me an emergency supply.
