Dr. De Long and his staff are the best. I never thought a visit to the dentist could be pleasant until my first visit with them. I really appreciated how Dr. De Long made an effort to explain to me everything I needed to know about the status of my teeth. I strongly recommend him.

He is hands down an amazing dentist and his team is super friendly and knowledgeable. They take the time to get to know you as patient by asking what you love and hate about going to the dentist to make your visit as enjoyable as possible. I definitely would recommend Dr. De Long!!

My family and I have been coming to Dr. De Long’s office for over 20 years. Dr. De Long and his staff provide excellent service. I recently had a medical emergency where I needed dental work done immediately. Dr. De Long was able to see me within an hour of the incident. I don’t know what I would have done without him and his staff. He genuinely cares about his patients, and I would recommend him to anyone.

He’s the best dentist I’ve ever had and I’ve had a lot of dentists over the years. I wish I’d found him years ago. He’s exceptional, extremely competent/technical, caring and very gentle. I’m a big wuss when it comes to the dentist, but I have no fears about going to see him. His staff are also wonderful.

Dr. DeLong provides a very high quality of dental care. He’s done root canals, crowns, fillings and some cosmetic dentistry on me over the past 20 years. He never pushes procedures you don’t need. The support staff are all friendly and professional. I highly recommend him.
