Patient Testimonials

He's my favorite doctor! And I have had many in my life. He's got a great, upbeat personality. He's done two colonoscopies for me and everything went great!

- Dr. Michalak's Patient

Dr. Michalak is my Hero! I have had him for years concerning stomach issues, colonoscopies, & EGDs. In 2016 after scheduling appt, discovered cancer & did a resection for an 18" tumor! I'm alive because of him. No doubt he is the best, very caring, great humor! He is very busy, in big demand, but worth the wait.

Dr. Michalak was great. He diagnosed a condition that I've suffered with for quite a while quickly, explained the condition and treatment very well in a manner that was easy to understand .
