Northern Colorado Anesthesia Professional’s strength lies in its people. We are a team of experienced anesthesiologists and CRNAs supported by skilled business professionals. Collectively we deliver coordinated and effective care for our patients inside the procedural suite and efficient practice management outside the clinical environment.
What do NCAP anesthesiologists do? NCAP anesthesiologists are board certified or board-eligible physicians who may have completed additional fellowship training that advances their knowledge and skill in a specialty area:
Pediatric Anesthesia
Cardiac Anesthesia
Critical Care
Pain Medicine
Add more specialty areas
Whether personally providing anesthesia or medically supervising CRNAs, the anesthesiologist ensures the safety and well-being of their patients before, during and after a medical procedure.
What do NCAP CRNAs do? Certified Registered Nurse Anesthetist (CRNA) staff are part of the overall care team. Board certified and highly skilled, NCAP CRNAs practice in collaboration with a physician anesthesiologist and/or surgeon in providing safe, evidence-based care.
