Carina Kee, DO

I am proud to be joining the Optum OBGYN group.

I grew up in Golden, Colorado, and went to CU Boulder for biology and Chinese language. I completed my medical school at Rocky Vista University in 2018, and did residency through Spectrum Health in Grand Rapids, Michigan.  

I strive to be a partner in your medical decision-making, and I look forward to building strong relationships with the women and families of Colorado Springs. My special areas of interest are high-risk pregnancy, minimally invasive surgery, and contraception.

Matthew Moore, DO

Growing up, I admired my grandfather’s medical practice and also desired a career where I could provide a meaningful impact in people's lives, so I chose medicine. I am a graduate of Philadelphia College of Osteopathic Medicine- Georgia Campus. While I was in college, I joined the U.S. Air Force, which ultimately brought me to Colorado Springs for the first time in 2013. I was stationed at the Air Force Academy as a Flight Surgeon, a medical officer for pilots, until 2017.

Lindsy Brickell, DO

I moved to Colorado Springs after completing my pediatric residency at Maria Fareri Children’s Hospital, just outside of New York City. Prior to that, I attended medical school in Parker, Colorado at Rocky Vista University’s College of Osteopathic Medicine. Pediatric primary care is my passion because I love being able to watch children grow and support their families along the way.

Derek Hatch, DO

I’ve wanted to be a ‘kid’s doctor’ since I was young, and now I’m lucky enough to have my dream job! I grew up in Mesa, Arizona and completed medical school and residency in Texas. It was my honor to serve in the United States Air Force and while stationed at the Air Force Academy, my family and I fell in love with Colorado Springs and decided to call it home. I love kids and my wife would agree I am just a big kid at heart. I believe that optimal care for each child is achieved through a partnership of trust between an empathetic physician and a child’s family.

Austin Vande Berg, MD

I grew up in Sioux Falls, SD where I attended Augustana College studying Biology, Philosophy, running Track and Field, and Cross-Country. I went on to complete Medical School at the University of South Dakota and my Pediatric and Adolescent Medicine Residency at the University of Nebraska before moving to Colorado Springs in the fall of 2018. Along they way, I taught high school, played fiddle in an indy band, and traveled to various countries doing medical work and cultivating a global perspective in medicine.

Rachael Degurse, MD

I was born and raised in Denver, Colorado. I chose to stay in Colorado for undergrad by going to Colorado College where I earned a Bachelor of Arts in Biology.

Khrystyl Pepi, MD

I have always had a passion for science and service. To me, the field of medicine blends the two. Family medicine has the added benefit of serving the whole person and the whole family. I have a special interest in children and adolescents, as well as preventative care and women's health.

Born and raised in the Southwest, I have a love of the outdoors and nature. Colorado Springs is the perfect place to explore both of these.
