“If I were to have open-heart surgery, I would want Dr. Peterson as a doctor. He has the most gentle hands, I don’t think he has broken anything ;) ”​

“If you’re looking for a friendly, full-service, one-stop tooth shop, family dentist office, then you’ve found it. I don’t think I’ll ever be able to say that I LIKE going to the dentist, but Dr. Peterson and his capable staff make it about as pleasant of an experience as possible. They’re knowledgeable and courteous; but that’s nothing new. They’ve been the same knowledgeable and courteous staff since my family started going to NW Smile Design back in 1996. I like consistency. There’s only one down side: the afternoon appointments tend to fill up fast, so bring your calendar. Nevertheless, time after time they’ve always greeted me with a warm smile. In fact, I almost LIKE going to the dentist!”

“Best dentist office I have ever been to. They send you a first-time patient welcome packet in the mail, which is extremely organized and very professional. Upon entering, the lobby is warm and not surgical like so many others, and there is a nice TV and a Keurig coffee machine for your enjoyment. Everything is very clean. They have state-of-the-art equipment and procedures. I found it very intriguing how they guided me through the post X-ray process, explaining what each finding meant. A lot of dentists will leave you waiting forever, but I had a hygienist with me at all times. Her name was Shannon, and she was wonderful. When I was leaving, they gave me a gift, which I thought was very nice. I honestly think that this is not only one of the best-run dentist offices I’ve ever been to, but also one of the most professional and good-quality businesses I’ve ever been to. I recommend Dr. Peterson and his staff to anyone in the Marysville greater area who is looking for comfort when in the dentist chair. Wonderful experience!”

“I started going to NWSD because my husband recommended it. So far, Dr. Peterson seems to try to get the best technology available to meet customer needs without going overboard. Their cleanings are useful. My dental hygienist is friendly and personable. I never feel like they are pushing services, but they answer questions and provide direction when you ask. The front office is friendly and professional. They have always been on time. I feel like I am in and out promptly for my cleanings. :) ”
— S. Wilson

“Dr. Peterson and his staff work on all the smiles in our family. We enjoy the service and friendly staff. The appointment reminders that are sent out in various ways so we don’t forget an appointment are a great help in our busy lives.”
— Mark

“I’ve been going to Northwest Smile Design since I was three years old and I have always been pleased with the service and quality I have received. Dr. Peterson is an amazing dentist who is very precise with his work and always does what’s best for the patient. I will continue to go to this dentist for many years to come and I am very satisfied with the staff of Northwest Smile Design.”

“Whether it is a cleaning or a procedure, I always get the very best care. Dr. Peterson is also constantly updating his skills and materials used for treatment. I have been a long-term patient, and plan on keeping it that way! I highly recommend Northwest Smile Design.”
— John

“I had been putting off getting a bunch of work done for quite a while. I found this dentist online and am glad I did. Hands down the most positive experience I’ve ever had at the dentist. I no longer have any anxiety about seeing the dentist. Dr. Peterson and his crew are the best. After several visits over the past few months, I have nothing but confidence in their abilities and expertise. A+ ”
— Ryan

“I’ve been going to Dr. Peterson for the past six years. He not only listens to your dental concerns, but you’ll also be in the best care with his expertise. His staff is friendly and it is easy to get appointments that you want.”
