Dr. McGuinn was born in Owensboro, Kentucky to a delighted Irish American family on St. Patrick’s day, and was named Erin (Gaelic for Ireland) as an homage to her roots. In fact, her father is a genealogist, and Dr. McGuinn can tell you who exactly she’s descended from on the Mayflower! 

She and her family moved to Pueblo, Colorado, a few years later, where Dr. McGuinn spent her childhood. She graduated from Centennial High School (go Bulldogs!) and went on to Colorado State University in Fort Collins, from which she graduated with a bachelors of science in environmental health and a minor in Spanish language.  During her time at CSU, Dr. McGuinn studied abroad in Guadalajara, Mexico and went on to collaborate on an international research project in a rural Nicaraguan village, where she spent two summers there as a translator for the project.  This experience was profoundly impactful and she quickly realized her calling in life was medicine. 

Dr, McGuinn attended the University of Colorado School of Medicine and spent several months during medical school in Guatemala and Honduras doing public health research and outreach. She graduated from medical school with distinction as a member of the Alpha Omega Alpha Honor Society and went on to complete a residency in Internal Medicine at Vanderbilt Medical Center in Nashville, where she learned to love country music! 

Dr. McGuinn knew she wanted to spend the rest of her career in Colorado and so came back home to complete her fellowship in cardiovascular disease at the University of Colorado, graduating in 2019. She was humbled to receive the  “Most Outstanding Fellow” award at graduation. She then completed an additional year of cardiology fellowship training at the University of Colorado in cardiac CT and MRI in 2020. 

Dr. McGuinn enjoys spending her free time in the great outdoors with her spirited, forever young 12 year old blue heeler and enjoys biking, skiing, hiking, and her favorite sport, basketball. She also enjoys traveling; some of her most memorable trips include backpacking through Central America and sailing to Cartagena, Colombia.

She is thrilled to have joined Western Slope Cardiology and is excited to utilize her knowledge of advanced cardiac imaging to better serve patients in the Valley.
