Definitely do not recommend Dr. haydek. If he can't figure out your problem he's like duh. Go to your medical dr.He will not even tell you to your face he will just leave a note on your chart.I have been going to him for about 15 years due to ulcers he's put me through several test and he makes you fill like your always doing something to cause your problems But the bad thing is when he's through with you his reply is go to Vanderbilt no referral no nothing. And yes he gets paid I have Ins.
Nationally recognized expert in treatment of Barrett's Esophagus. Staff at Thompson Laser Center excellent in every way. Very patient-friendly, low-keyed environment.

Dr. Haydek and his nurse Jennfer are absolutely the best. Dr. Haydek took his time examining me and explained all aspects of tests, test results and all the procedures he performed. He was kind and I believe he saved my life. He was the last of many doctors who couldn't find out what was wrong with me. I lost over 20 pounds and was not hopeful and very depressed. Dr. Haydek had a sense of urgency and took care of me immediately. Jennifer was the person who got me an appointment quickly.

I've been a patient of his for nearly 15 years and he is one of the rare ones, who treats you with respect.
