Our Team

David W. Mueller, DC


Dr. Mueller, a native of Salmon Arm, BC, attended the University of British Columbia to complete his Bachelor of Science degree. After his undergraduate studies, he traveled the world, spending time in New Zealand, Australia and the South Pacific. Upon returning to Canada, Dr. Mueller pursued his Chiropractic degree by moving across North America to the beautiful state of New York.

Dr. Mueller graduated Magna Cum Laude from New York Chiropractic College in Seneca Falls, NY in 2004. Before graduating Dr. Mueller had the privilege to complete an internship at the National Naval Medical Center in Bethesda, Maryland. During this internship, Dr. Mueller worked as an integral part of a multi-disciplinary team to provide care for active and retired military personnel, which exposed Dr. Mueller to the benefits a patient receives from a multi-disciplinary approach to healthcare. It was this experience that encouraged Dr. Mueller to strive for the best possible care of his patients.

Dr. Mueller endeavors to ensure that the diagnosis of the patient’s condition is not only accurate, but that it is explained in an understanding manner to the patient. His treatment plans are designed to correct the condition as efficiently as possible, with emphasis on comfort and patient satisfaction. With home care recommendations, orthotics, nutritional advice and an exercise plan, Dr. Mueller’s treatment plans ensure a healthy lifestyle away from the chiropractic office.

Dr. Mueller enjoys spending time with his beautiful wife, Erin and his sons Jaxson & Bode. He is an avid fisherman, amateur woodworker, and enjoys participating in most athletic activities.

David Rose, R.Ac. TCMD

Acupuncturist & Herbalist

I have been involved with acupuncture and traditional Chinese medicine since 2001.

One of the most common questions patients ask me is, “How did I get into acupuncture and traditional Chinese medicine”? This is the most common question aside from, “does acupuncture hurt”? Which by the way… you barely feel the needles at all!

So to answer your question….. my love for kung-fu as a teenager, my interest in Chinese culture and philosophy, my desire to help others, and my values regarding health all seemed to merge together nicely in this career that I have chosen. I suppose all of these factors ultimately led me down this path.

Since acquiring over a decade of clinical experience as a practitioner I have dedicated myself to learn effective and efficient techniques to help you recover in a timely manner.

Acupuncture and traditional Chinese medicine have not only helped thousands of my patients regain their quality of life, but it has helped me, and my loved ones as well.

I believe there is a very high chance it can help you too!

And just in case you are unsure or have questions, I am happy to put time aside for you to come in and meet me, and ask your questions directly.
