Dr. Klempner has been very caring and helpful. When my son Matthew was involved in a bike accident, Dr. Klempner called on a Saturday and set up a visit with an oral surgeon. He not only helped Matthew, he gave me peace of mind!

Brian is doing Wonderful! I was expecting his first week with his new appliance to be a horror. Much to my surprise his adjustment is going extremely well. From the consultation on, Dr. Klempner and his staff have been fabulous. All of them make this a terrific experience for my son. I wish I knew of Dr. Klempner when I had my braces!

Coolsmiles office is great. My daughter was 8 years old when we were recommended to come in.  I thought she was too young. When I was a kid they waited for all the adult teeth to come in, pull what's crowded and put on braces. My daughter didn't need braces because of early services.

Dr. Klempner is the most caring, kind and honest man! My son always had a good experience with him and his office staff. We only wish every dentist office was run the way his is.

Coolsmiles is such a great place. Their experience is great and they make people all around smile. If they had to they would take their own time and make the best of it. It's really a place where everyone is always happy and smiling.

From the very first encounter it has been nothing but a pleasure. The professionalism of Dr. Klempner and his staff are unsurpassed! The open and friendly atmosphere puts the children and parents at ease. What a wonderful place to help your child's smile!

I wish Dr. Klempner was practicing years ago when I was growing up.

My eight year old daughter, Jessie, has been a patient of Dr. Klempner's for 10 months and I can't tell you what a positive experience it has been for both of us. His friendly and professional staff were able to put any of my daughter's fears at ease. She is happy and proud to wear her appliances and show them off to all her friends.

Hi, my name is Jessie, and I am eight years old. I like coming to Dr. Klempner's office. I love my appliances. They are so cool and fun to have.

Our experience with Coolsmiles has been wonderful! We have never dealt with any doctor's office where every person on the staff (from the receptionist to the orthodontist) is so caring and gentle. They can make the most timid patient feel calm and relaxed. Thank you for a wonderful experience!

Dear Leon,
I made a poem just for you. First the teeth look bad. Leon fixed that problem. The kids teeth are better, they all have smiles. Dr. Leon goes home after a hard day's work. He hops into bed and closes his eyes, good night. Knowing he did everything right.

I am approaching the end of one of the most fantastic experiences of my life. As a mature adult, with 3 grown grandsons I was not sure how this new experience would work out but it has turned out to be "THE BEST".

From the moment I entered the office for the first time I felt welcomed, comfortable and excited about my New Adventure. I chose Invisalign because I did not want to draw attention to the fact that I was wearing braces. It was fun sitting in the dental chair surrounded by children of all ages. Since I am a retired teacher I was totally comfortable in this setting. The Staff is among the best I have ever encountered in a dental practice. They are friendly, considerate and relaxed as they take care of us.

I am also honored to know Leon because I think he is the most altruistic person I know. Every year, for about 2 weeks, he donates his expertise and time to surgically help children in Honduras who have been born with cleft palates. I think that is so commendable. And those children will never really know what a kind, loving and caring person their doctor was. It has been a great ride and I wouldn't have missed it for the world!
