Hear What They are Saying

Dr. Thousand is amazing! Their office is brand new and so welcoming. As a dentist we only refer to Periodontal Associates Littleton for the care of our patients. They have such a high clinical skill and take care of you the whole way through.

Dr. Thousand and his office were absolutely wonderful! Easy to schedule appointments and never having to wait as he’s not over booked. I understood my procedure and knew what to expect the entire time. I’d definitely recommend him and his office to anyone.

Carol B.

I was very nervous about gum surgery. Dr.Thousand and his staff were amazing! He did a great job!! My gums are so much better. If I had to do it again, Dr Thousand is the guy to do it!! His office is wonderful and all the people who work there are awesome!

Jeanne H.

Great professional office all around. Dr. Thousand is excellent and I especially appreciate my dental hygienist who is the best I’ve experienced during all of my periodontal work over the years. An all around exceptional group for dental health care.

De E.

I needed grafting on three teeth. Dr. Thousand was great throughout. The procedure was intense, but he prepared me for everything. I was worried one day and they had me come in right away and put me at ease that everything was fine.
