Clinical Interests

I was born and raised in the beautiful state of Colorado. I traveled all throughout the country, but did not leave the state until medical school when I moved to the island of Grand Cayman. I spent 18 months enjoying a different kind of beauty while learning medicine. Then I spent the next few years of my life living all over the country from Chicago to Orlando and settled in Arizona to complete my residency. I spent three wonderful years at the Phoenix Baptist Family Medicine Residency where I was able to follow my passion for full spectrum medicine and women’s health. I am now grateful to have a position with the same residency, now known as Abrazo Central Family Medicine Residency.  While in medical school I was able to complete an MBA. Outside of medicine I enjoy playing the flute in a community band, crocheting blankets and enjoying the outdoors at any opportunity.
