About me
I was born and raised in Denver. After spending my undergraduate years in Vermont at Middlebury College, I returned to Denver for medical school at the University of Colorado School of Medicine. I then left the state again for training followed by a faculty position at the University of Michigan. While my family and I loved Ann Arbor, the allure of Colorado was too great and we ultimately transitioned back to Denver in 2015 when I took a position with Kaiser Permanente. I see patients at Good Samaritan Medical Center and Saint Joseph Hospital. I have authored more than 30 peer-reviewed publications and continue to actively participate on a national level in the American Society of Radiation Oncology in an effort to continuously improve patient care.
About my practice
I am here for you—to listen, to advocate for you, to formulate and coordinate a treatment plan based on your needs and goals, and to execute that plan. I have access to the latest state-of-the-art treatment equipment to provide you with the best outcome possible. I believe in open, two-way communication so you fully understand and agree upon your personal care plan. I work as a team with our specialists, pharmacists and others to coordinate your care.
How I thrive
I have three young girls who keep me quite busy outside of work. As a family, we love spending time outside, skiing, biking and swimming.

If you request it, your request for hard copies of the provider directory remains until you leave Kaiser Permanente or request that hard copies be discontinued.
Kaiser Permanente considers the following factors as it builds and maintains provider networks:
- Size and demographics of the population to be served
- The inventory of provider and facility types required to serve the population
- Practitioner-to-member ratios and geographic access standards
- Application of credentialing criteria encompassing but not limited to educational training, licensing, professional experience, board certification, and professional references
You may select a primary care provider (PCP) from family medicine, pediatrics, or internal medicine. When possible, we encourage you to choose a PCP whose office is in a Kaiser Permanente Medical Office Building. You may have a higher copayment and/or coinsurance with certain PCP providers.
