Jacob Jarvis, DMD


I am excited every day that I go to work because I always get to meet new people, and not many can say that. I meet young kids and older adults and watch awesome transformations. It is important to me that each patient understands his or her treatment. I treat every patient like my own child or family member.  I have always been interested in helping people live better, healthier lives. Working with motivated people is fun!

I attended Boise State University where I earned my Bachelor of Science degree in Biology. I continued on to the University of Connecticut, graduating with my Doctorate of Dental Medicine before completing my Master of Science degree and orthodontic residency at Marquette University.

I am an active participant in continuing education and enjoy learning about new and progressive technology. I love learning more about Invisalign®, Damon® System, and temporary anchorage devices. All this knowledge directly relates to the quality of care and results my patients can expect to receive.

I have lived my entire life in Boise, except for my time in school. My wife’s name is Colleen. She is an Irish spitfire from Wisconsin. We have three boys, Noah, Liam, and Roan, who are all full of energy! We also have a dog named Otto!

I love to ski, snowboard, cross-country ski, and anything outdoors in the snow. I love to bike with my kids around Payette Lake and the surrounding area. I am very active with my family, coaching in my sons’ youth leagues and sponsoring their activities. I also enjoy date nights with my wife and riding around town on my Harley.
