Patient Testimonials

"I’ve been going to Dr. Gleixner for 8 years. My husband’s family has been going there for decades. Dr. Gleixner is amazing and his staff, both front and back, are incredible! I highly recommend his practice!"

Amanda I.

"Very caring and wonderful staff. My husband's been going to Dr. Gleixner, since he was 14 years old and he is now 45. He's compassionate, caring and sympathetic and does bend over backwards to help his patients. He makes you feel like he's part of your family talk to you like a human being."

Angie P.

"Dr. Mark and his staff are the greatest! They are all so genuinely happy to see me and my family. He's been my dentist for 30+ years and my whole family goes to him. Today when I brought my youngest for an early appointment filling and I hadn't had my coffee, the front desk gals fixed me right up with a cup!"
