USAP-Colorado Logo


USAP-Colorado is a physician-led partnership of board certified anesthesiologists, care team members and practice management experts from Greater Colorado Anesthesia (GCA) and South Denver Anesthesiologists (SDA).


Our team of experienced professionals have served this area for more than four decades through two strong anesthesia groups that have now come together. From this new foundation, they will continue to meet the needs of our community well into the future.


We are now part of a national network of leading anesthesia providers and have the ability to truly transform anesthesia services across the country. We have access to new resources and best practices that will strengthen our ability to meet the demands of our community. With more than 3,000 team members, USAP is one of the only national companies exclusively dedicated to the practice of anesthesiology.


In addition, our integration as USAP-Colorado will allow us to further build out our service delivery model so that as the facilities we serve expand and grow, we can support their growth with dedicated teams.  This will maintain the important relationships in place with surgeons and facilities to ensure clinical consistency and a continued high level of patient care.


Even though our name has changed, USAP-Colorado remains a Colorado-based practice. You will still work with the same, high-caliber teams that understand the needs of Colorado patients, surgeons, payers and health-care facilities. We remain rooted in—and committed to—Colorado.
