Mara Additon, MD is a board certified general and trauma surgeon from Boulder, CO. She aspired to become a doctor at an early age and at fourteen read an article in National Geographic about surgical advancements in the treatment of brain injury. This article made a significant impression on her and solidified her desire to become a surgeon. She chose general surgery because she enjoys the day-to-day variability and the broad spectrum of surgical conditions that the specialty presents.

Mara attended the University of Oregon and earned a Bachelor of Science in biochemistry and math while also playing collegiate division 1 volleyball. She went on to the University of Colorado where she earned her master’s degree in biostatistics. Her thesis focused on survival factors in cardiac-related surgeries. Prior to medical school, Mara conducted research and statistical analyses on heart and liver transplantation with the division of transplant at the University of Colorado. She completed medical school and her residency program at the University of Colorado.

Dr. Additon chose to practice in southeast Idaho because she, along with her husband, Aubrey, and their two young boys, loves Pocatello’s small-town feel an the many outdoor activities Idaho has to offer.

Dr Additon LISTENED. In the last few years ive had less of thst than I should have from professionals. I appreciate so much that Dr Additon listened and acted on her training to get the tests I needed and the surgery I needed. Thank you!!

Very nice and informative

Dr Addition made me feel comfortable and was able to answer all my questions. Still have a ways to go before I am back to normal, but I am confident she will help me get there.

Could not recommend Dr. Additon any higher. She has done two procedures for me with outstanding results. 6 stars



This review is about my initial visit and pre-surgery consult. Dr. Additon was very cordial and professional throughout my visit. Since I am about to have my very first surgical procedure in my 57 years on this planet, I was sorta paying attention as I battled my nerves. I can’t say I left the office any less anxious than I did on my arrival, but I am fine with knowing that what needs to be done will hopefully resolve my abdominal issues.

Dr. Addition explained things so well and called me back with my results when she had to reschedule my checkup.
