What Our Patients Are Saying
Dr. Kassem is the best! My first appointment was in 2001- he is a gentle, professional with a great touch. Many people hate going to the dentist- this I don’t know why- if everyone’s dentist was like him, everyone’s smile would be happy & healthy! Thanks Dr. K!
My wife and have been going to Dr Gwaltney for years. My recent visit was for a root canal and I’ve always heard how painful the process can be. I would definitely say that was not the case for me. Dr Gwaltney explained everything to me and made sure I was comfortable throughout. I highly recommend, not root canal, but the professionalism and care!
I’ve been a patient of Dr. Kassem for 10+ years now. Every visit he and his staff has always been very professional, respectful, and friendly. Dr. Kassem is always thorough in explaining dental procedures and tips on achieving better dental health. I highly recommend Riverside Dental Family & Cosmetic Dentistry to anyone looking for dental services. If you are looking for a great dentist, please consider them!
Dr Kassem has been providing dental care to my whole family since he opened his practice many years ago. As much as I don’t like going to the dentist– with him, it feels more like seeing a good friend. I highly recommend Dr Kassem & his team.
Dr Kassem and his team are excellent when comes to dental care. Our family has been with them for years and won’t be switching. Highly recommend them for all your dentistry needs. They make you feel like family.

This is one of the best dental offices I’ve ever been to. The staff and Dr. Kassem are so nice and caring about the patient. I know when i sit in the dental chair with Dr. Kassem that I am going to get quality work with no hassles about extra things that I don’t need. I am a long time patient at this practice and tell all my friends to come here.
Dr. Gwaltney is very gentle and professional. He is simply the best dentist I have ever had. I was always terrified to go to the dentist, but since I’ve met Dr.Gwaltney I am happy and excited to have my dental check up. He is the best at giving shots, I didn’t feel any pain.
I have been with Dr. Kassem for 17 years and wouldn’t think about going elsewhere. He and Gladys are incredibly professional, but so caring that you want to give them a hug as you leave the office. Dr. Kassem goes above what is expected of a dentist and that is why I recommend him to all of my friends. He onced opened up the office on a major holiday to take care of a dental issue I had. You won’t find a more professional, humble, and caring dentist.
