It was great! There should be more stars! Always has been. I drive over an hour to each of my visits because of the car I get there.this time my service was with Crystal who handled my dental care delicately and professionally. My scaling treatment was very close to a dental massage. Do try them. Trust me…You’re welcome…

Everyone at this office was wonderful. From the office staff, the assistants, and Dr. Park. I felt comforatable and well cared for from my consultation until my final follow-up appointment for a gum graft procedure. When they tell you to trust the process, trust them. When they tell you not to peek, don't peek. I am very happy with my result, and would highly recommend them!

This team is fantastic! My son came home from college with a toothache and found out he needed a root canal. I called this office looking for an emergency appointment and spoke with Melissa. She was so friendly, expressing genuine care and concern, and quick to schedule him the same day. When we arrived, we were greeted as soon as we walked in the door. The office is bright and super clean. My son was quickly taken back to meet Dr.

O'Sullivan. He carefully examined the situation and was thorough in explaining different treatment scenarios before he started the procedure. He has a fantastic bedside manner and works with a wonderful assistant, Janine. They really made my son feel like he was the most important person they saw all day even though they do this all day, every day. The care was exceptional! Cyndi helped us check out at the end of the appointment and she was so kindhearted and friendly. Phenomenal 360 degree patient care!! THANK YOU!

This was my first time in this office and I cannot say enough good things about it. Every single person was so kind, courteous and helpful. I was very nervous about the procedure and Dr. Kleiman put me right at ease with his professionalism, humor and friendly manner.

The hygienist even rubbed my shoulder to help me relax which I thought was so sweet. The entire office is beautiful, and I was even offered a delicious Crumble cookie to take home. I was extremely pleased in every way and would highly recommend Dr. Kleinman and his staff!
