What Our Patients Are Saying

Dr Vassallo is a gem. His compassion and dedication is heartwarming. His office staff are always eager to meet the needs of the patient. There's a special lady at the front desk, Vicky, who always responds quickly to any call. I feel so very fortunate to have Dr Vassallo taking care of my complicated dental needs.

Great family dentist! You are not just a number. They treat you like a human being. They truly care about their patients! I've only had one dentist since I had teeth but since he retired years ago, I tried many other dentists. Dr. Vassallo is the one I'm sticking with. Such a calm atmosphere. Never over booked. They never rush you in and out just to get to the next person. I highly recommend Dr. Vassallo to be your dentist!

Abigail K PATIENT

He seemed very knowledgeable and very willing to work with his patients to find solutions that actually work and are cost effective. He also is very thorough with his exams as well. He makes you feel like you're in good hands and he also is very willing to explain everything to someone who is not knowledgeable about dentistry. Not only that, but he actually cares to see if his treatment work, as demonstrated when he asked me to call back in 2 weeks to make sure all is well. Very satisfied!

Sally M PATIENT


I went to Dr. Vassallo with pain in a molar, he reviewed my x-rays and recommended I see a specialist for a possible root canal. This was impressive because he also does root canals. I appreciated the fact that he was confident enough to refer out instead of doing a procedure he wasn't 100% comfortable doing. Most other dentists would have done the procedure and hoped for the best. I returned for a post and crown a few days later. I prefer not to have any anesthetics if possible, Dr. Vassallo agreed to insert the post and crown with out anesthetics and was as gentle as could be. No pain during the procedure and the slightest bit of soreness the next day. Thanks for making what most people consider a torturous procedure a very manageable one! I'd love to say pleasurable, but it was still several hours in a dentist’s chair with sharp objects in my mouth! So manageable will have to suffice!

Doctor Vassallo and his staff are the most welcoming group of professionals I have ever met! As soon as you walk into his office you are greeted by his wonderful receptionist who immediately makes you feel like family. Coming from someone who is very nervous about going to the dentist, each time I have gone to see Doctor Vassallo he has immediately made me feel relaxed. He's patient and kind, and never seems annoyed or frustrated with my anxiety . Instead he talks me through it. I would absolutely recommend (and I have!) Doctor Vassallo to my family members, friends and Coworkers.

Dr. Vassallo is the best dentist I've been to by far. Professional, courteous, and gentle, he listens to you and explains in detail all of the procedures so that you know exactly what to expect. He takes his time with you and you are never rushed out of the office. His staff is excellent. Vicky at the front desk is friendly, patient, efficient, and helpful. Mellisa the hygienist is outstanding - very gentle, pleasant, and thorough. The office has a family practice feel and they make you feel part of their family. They all do their best to make a visit to the dentist as painless as possible.

Dr. Vassallo and his staff are the best. I never write any of these but felt that I had to let people know how great they treat you there. The very definition of a family practice. Dr. Vassallo is an awesome dentist, who has a terrific bedside manner. He actually talks to you like a person and explains everything that needs to be done. His wife Vicky handles all the office stuff and she has helped us out with insurance issues, scheduling problems and just always seems to go the extra mile for us. Melissa, the hygienist is just awesome too. I know it sounds cheesy but every time I visit them it's like I'm visiting family. They're just good people!
