Doctor Mark Guelzow is an amazing doctor who truly cares about his patients. He’s patient-friendly, takes time to listen to every concern, and explains everything clearly without rushing. You can tell he genuinely wants the best outcome for you. I’ve never felt more comfortable or cared for in a medical setting. Highly recommend Dr. Guelzow to anyone looking for a compassionate, skilled physician.

Worst experience I have ever dealt with in my life. Calling 10+ times to have a script sent over. Changing the test to oral the day of so I have to reschedule and miss work. Avoid this place like the plague

I’ve been going to this this doctor for years. Unfortunately I arrived 10 minutes late today. I had been in the hospital till very late due to complications with my pregnancy. There was no one else in the waiting room and they turned me away. I’m disappointed at the lack of compassion. Will not be treating there again.
