Unlike many physicians, Dr. Valachi understands the connections between Sleep Bruxism (clenching and grinding), TMJ problems, headaches, and Sleep Apnea. His effective and revolutionary Sleep Apnea program is designed to relieve patients of their chronic pain and sleeping issues. Dr. Valachi’s current practice focuses only on the treatment Sleep Apnea and orofacial pain symptoms. This medically oriented approach allows Dr. Valachi to study the common conditions related to pain and Sleep Apnea, while providing patients with a comprehensive clinical experience.

Ricky Young

Dental Assistant

My name is Ricky and I was born and raised right here in Oregon. I love this state and can’t imagine living anywhere else. Working out and cooking are two of my favorite things to do, especially if I’ve had a stressful day or week. I also love binge watching a good series or a great movie. Read More

I feel so fortunate to have found a place to work like Dental Sleep Apnea Clinic. I love treating all the
people who come in because I know I’m part of the reason they’ll be able to live longer and more
fulfilling lives. Since working here, I’ve realized how important a good night’s sleep is and I actually suffer from snoring. I can’t wait to get my own dental appliance so that I won’t be chasing my girlfriend out of the bedroom anymore.

Davianne Myers

Dental Assistant

Davianne joined the practice in 2018 and was a natural with helping patients understand oral appliance therapy. She knows that without good sleep and good sleep quality, she wouldn’t be able to keep up with her 4 kids and fiancé or be the best Mom she could be. Read More

Davianne is passionate about working here because she loves seeing our patients strengthen their lives and bettering their health with the treatment we are providing. When she’s not busy working or being a mom, she enjoys camping, cooking and outdoor sports.


My 14 years as a Sleep technologist have given me the ability to better understand and believe that quality sleep is the foundation to our overall health and wellness. Read More

Sleep technologists do not get the education for oral appliance therapy and so may have a mindset that oral appliance therapy isn’t effective or comes with greater challenges than PAP therapy. However, becoming part of the Dental Sleep Apnea Clinic team has helped me gain new knowledge and witness firsthand the impact oral appliance therapy can have in a person’s life. Our team is 100% devoted to our patients, taking time to educate and ensure patients leave feeling confident and heard. I am happy to be working with a team so enthusiastic and passionate about not only treating patients’ sleep apnea but improving their quality of life.


For the first time in my life, I LOVE coming to work. I have a background working in retail and sales, where I was just a number, customers were just dollar signs, and caring for them had limitations. Now I work with a team that appreciates one another, trusts one another, and respects one another. I get to see people’s lives change, right before my eyes! Read More

 I see patients come in, whom I must repeat simple instructions to, or who can barely remember what day of the week it is. Then I see them a month later, and they are smiling, alert, making conversation, and seem… lighter. And WE helped that happen! Dr. Valachi leads this team with knowledge that he is always sharing with us, kindness that reverberates all around the office, and a belief in what we do and the difference we make in patients’ lives, and that is contagious.
