Board Certified Colon and Rectal Surgeon

Portrait of Dr. Forstner

Dr. Forstner is a board-certified colon and rectal surgeon, who founded a thriving female colon and rectal practice after returning to the Valley in 2006. She received training at Mayo Clinic Scottsdale after attending medical school at the Mayo Clinic in Rochester, MN, and received her specialized surgical training with the Colon and Rectal Clinic of Orlando. She specializes in the treatment of colon and rectal and anal cancer, in particular the robotic and laparoscopic or minimally invasive surgical approaches to this disease. She helped to bring to the valley a revolutionary minimally invasive approach to rectal cancer resection, called Transanal Endoscopic Microsurgery. She performs screening colonoscopies and treats all forms of benign colon and anorectal disease - including anal pain, diverticulitis, hemorrhoids, fissure, fistulas, fecal incontinence, rectocele, rectal prolapse and constipation. She continues to pursue cutting edge approaches to issues such as robotic surgery and the sacral nerve stimulator for fecal incontinence.

Dr. Forstner was chair of the Cancer Committee until it dissolved and participated in the Medical Executive Board at Banner Thunderbird Hospital from 2008-2017. She is an adjunct professor for AT Still University and trains PA students for this school and for Midwestern. She is a Fellow of the American College of Surgeons and American Society of Colon and Rectal Surgeons. Dr. Forstner is also a member of the Society of American Gastrointestinal Endoscopic Surgeons. She is on staff at hospitals in Phoenix, Glendale, and Sun City/Peoria. She spends what free time she has working on "Por Ellos," her Nicaraguan charity, and traveling, singing and hiking with her husband.

Shannon S. - "Dr. Forstner-Barthell is an AMAZING doctor. There is no one else who I would trust for my care. We found a large mass on my ascending colon that could not be removed via colonoscopy so I had to have surgery. Dr. Forstner-Barthell was with me every step of the way. She took her time in listening to all of my questions and was available any time I needed her. Every facility and staff that I came into contact with had nothing but praise for Dr. Forstner-Barthell. We caught the mass early and no cancer. I will be a life long patient of Dr. Forstner-Barthell. She saved my life. I am grateful to and for her. Thank you Dr. Forstner-Barthell!!!"
