Your Local Dermatology Team in Montrose, Colorado

Dr. Renata Raziano

Dermatologist

Dr. Raziano a is a native of New Jersey where she grew up in a suburb of Philadelphia. A strong interest in science and the opportunity to play college basketball led her to University of Pennsylvania for her undergraduate degree. After college she attended medical school at Emory University in Atlanta where she completed both MD and PhD degrees. While in medical school she decided to pursue dermatology as a career due to the variety of patients and conditions treated. Skin diseases are very diverse and affect everyone from infants to the elderly. In addition, dermatology allows her to see patients and perform surgeries which requires a balanced skill set and provides an enjoyable mix within her medical practice.

After completing her dermatology training she came to Montrose and opened her practice in 2012. Her husband is a radiologist at Montrose Memorial Hospital and after living in large cities for many years, they are happy to be raising their family in a small town.

Outside of medicine she enjoys mountain biking, road cycling, cross country skiing and other outdoor adventures with her husband and two young sons. An avid cyclist, she donates her time as a board member of the Colorado Plateau Mountain Bike Trail Association (COPMOBA).
