Internal Medicine, Family Medicine

Theresa Holsan began her nursing career over 30 years ago working in OB-GYN. She then realized her love was primary care and has been working with entire families, including several tri-generational ones, for more than 20 years. She sees children from the time they are born and adults through their twilight years.

Being a Colorado native and life-long learner Theresa opted to earn her degrees in Denver; her advanced degrees include a Master’s in Nursing, specializing as a Family Nurse Practitioner, from Regis University and a Doctorate in Nursing Practice from the University of Colorado Health Sciences Center. She has created a “New Parent’s Handbook”. Her doctoral research focused on improving hypertension; she presented the findings locally, nationally, and internationally. She has presented on improving End-Of-Life care for patients to nurse educators. She has served multiple terms on the Colorado Nursing Board. Although she has retired from teaching in the classroom at Regis University, she remains a clinical faculty.


Specialties: Theresa works to partner with patients to help them reach their healthcare goals. In addition to routine medical care, she is trained to perform minor office surgical procedures and many GYN procedures such as skin biopsies, trigger point injections, Nexplanon and IUD insertions, colposcopies (to evaluate abnormal paps) and endometrial biopsies (to evaluate post-menopausal bleeding). Theresa is board certified in Family Practice.
