Met with Dr Streitz per referral and after initial checkup my problem was less critical than I believed. Dr Streitz and his staff are quite comfortable to work with and Dr Streitz is quite professional and easily understood my concern. I would see him in future and have no hesitation about seeing him again.

Best all around quality care. From the moment you’re greeted by the receptionist (Cheryl) until Dr. Mark finishes his procedures you are treated with top quality professionals. I grew up having Dr. Richard (Mark’s dad) as my dentist & am so glad to continue with Dr. Mark. both top notch in my book.

I have been going to Mark Streitz Dental for over 10 years. Dr. Streitz has always had my best interest in all that he has taught me about taking care of my teeth.
