Dr. Skyler Dumas, Chiropractor

Dr. Dumas was born and raised in Colville, Washington. His interest in chiropractic began after he was injured in football at the age of 12. He was fascinated by how his own chiropractor had healed him better than new. Through college he continued to grow his passion for the human body and health while playing collegiate basketball.  Following that he moved to Dallas, Texas to earn his Doctorate of Chiropractic at Parker University. He completed his residency under Dr. Moses at the Dallas VA Hospital and graduated in August 2016.  Dr. Dumas specializes in the Nervous and Musculoskeletal systems as well as nutrition and soft tissue conditions. This gives him the incredible opportunity to impact people’s health directly while spreading the message of true health. Nothing makes him happier than knowing he is giving someone their life back. During his spare time, he is an avid outdoorsman and has a love of basketball and exercising. He enjoys helping with youth basketball and spending time with friends and family.  Dr. Dumas is happy to be back in Colville and to give back to the community that has given so much to him.

Harley Oswalt, Chiropractic Assistant

Harley was born and raised in Prosser, Washington. After graduating high school, she went to school to become a dental assistant and worked at an orthodontist office in Tri-Cities, Washington for two years. She soon realized that the dental field was not what she was meant to do so she moved to Colville which has been one of her favorite places since she was little. This is where she was able to join the Monumental team, and is extremely excited to be able to continue to assist people in need. Outside of work, she spends her free time doing numerous activities outdoors, and playing with her dog. Harley is excited to see what Colville will bring into her life, and is happy to help out this community that will hopefully be her forever home.
