What Our Patients Are Saying About Us...


I'm very satisfied in the way...
 By Brian J. 
"I recently moved to Washington and I really needed a dentist. I had a terrible tooth ache that was bothering me for months. A co-worker referred me to Dr. Knaphus' office. The tooth started hurting so much that I decided I had enough. I called the office and made an appointment and in few days I was pain free.The removal wasn't traumatic or painful at all like some other experiences ... I was pleasantly surprised. I recommend this office to anyone.Thank you for helping me. I'm very satisfied in the way I was treated with kindness and consideration."

 By Charles O. 

"I'm very pleased and I felt very comfortable during my treatment at the office of

A-1 Family Dentistry.The staff was great, very friendly .The office is beautiful and simple, which I actually like about it and also very clean. I noticed that everything was impeccable when I used the restroom. And about my treatment ...Well I compare it with the earlier treatments that I have had. My teeth look so much better, I feel great when I smile,  and my level of confidence is way up there. l had porcelain veneers done with Dr. K. It was easy and it wasn't painful at all. I should have done this a long time ago. Before, my teeth were widely spaced and very stained. They were yellowish in color and it really did hurt my self-esteem a lot. After this treatment they are perfect. My treatment was very good, well organized, and easy to schedule. I 'll definitely be back."

 Wow, what a great facility

 By Ethele- May 18, 2010
"My whole family - myself, DH, and two 2.5 year-old toddlers - just visited Dr. Knaphus, after seeing the 5-star reviews here. For the toddlers, it was their first checkup ever. For me, it was my first visit in six years (no insurance), and for DH, it was his first visit in . . . well, a very long time indeed. Dr. Knaphus handled our laxness in our dental health gracefully and encouragingly, and didn't come across as nagging, preachy, or pessimistic. He was great with our toddlers, and did a full cleaning for one daughter - who did get upset, but calmed down once he started "playing" with the tools with her. The other twin threw a fit, but still got some tooth care - and better yet, is really excited about the dentist despite the fit. Our daughters have been very excited to have their teeth brushed and flossed ever since - and, since the dentist kept the visit very positive, DH and I are excited about being able to help them (and get our own dental hygiene on track again as well)."

 By Antony S.- May 13, 2010
"The office has a pleasant atmosphere, comfortable, the treatment room was also very nice. Regarding the staff and the service: everything was great from the moment I called to make an appointment. They were friendly, attentive, and efficient. Dr. K was polite, kind and considerate, and he seems to be a friendly person as well. And he actually listened to me. During my treatment I was able to relax, something that used to be so hard for me in the dentist's chair. I'm definitely a happy patient of this office and I would recommend it to anyone."
I am happy and grateful for being taken care of so well.
 By Mrs.J - May 12, 2010

"I suffered for years with gingivitis and bad breath. After receiving a postcard from this office, I made an appointment with Dr.Knaphus.Today I am happily taking care of my dental needs. They taught me how to thoroughly take care of my teeth and stop bad breath.They were great with me. With their help I got a beautiful smile and I feel much more confident to talk up close with people. Now I am no longer ashamed to smile .
