Patient Reviews

The best review we can receive is a healthy smile from our great patients. Below are just a few of the great testimonials we have received from patients at our dental office.

The staff was friendly and helpful during the whole process. Angela the hygienist took the time to explain the process of what she was doing and was incredibly thorough to ensure a proper job was done. Dr Zafir took the to speak with me about my results and discuss next steps. The whole process from start to finish was smooth and I felt very well taken care of. I would highly recommend this practice for anyone.

Caring and calming team!
Love Dr. Mark!
I’ve been with Dr. Jacobskind for 30 plus years and the transition to Dr. Mark has been seamless and positive.
My first visit and crown procedure today, as nervous as I was, was a success.

I’ve been seeing Angela for 15 years and I wouldn’t have it any other way. Angela is professional, personable and caring. Angela is the reason I’ve been staying with this dentist office for so long, I always know I’m in good hands. She takes care of me, listens to my concerns and I leave with the cleanest teeth! Angela is top notch and I appreciate her expertise.
