Patient Testimonials

Very friendly staff! The hygienist is very thorough with teeth cleanings and makes you feel welcome. Dr. Streitz is really knowledgeable about dentistry and is kind to all of his patients and staff.

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.

My experience with this dentist’s office was excellent as usual. The entire staff is more than accommodating. They are punctual and pleasant at each and every appointment. I am totally satisfied with their dental work and am pleased as well with their advice on how better to care for my teeth. I would highly recommend their services.

I recently switched to Dr. Streitz after almost forty years at my old dental office and I couldn’t be happier. The office is modern, super clean and doctor has new state of the art dental technology.

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.
