A Physician Shaped by
Curiosity & Commitment

Dr. Keller grew up in Connecticut and developed an early passion for science and sport — earning a spot on the Men's Soccer team at New York University while majoring in Biology. After NYU, he continued at the NYU School of Medicine, now ranked among the top medical schools in the country by U.S. News & World Report.

During medical school, Dr. Keller invested significant time in South America conducting medical mission work and research — an experience that deepened his commitment to accessible, patient-centered care. He graduated at the top of his class and was inducted into the Alpha Omega Alpha Honor Society, the highest academic distinction in American medicine.

"From sinus surgery to head and neck oncology, I want every patient to feel genuinely heard — and to leave with a clear path forward."

Dr. Keller completed his residency in Otolaryngology – Head and Neck Surgery at the Medical University of South Carolina, one of the country's most respected ENT training programs. He brought that expertise to Southern Colorado, where he now serves adult and pediatric patients across a wide spectrum of ear, nose, and throat conditions.

Beyond clinical care, Dr. Keller is an active researcher whose work has appeared in peer-reviewed journals including Clinical Otolaryngology, JAMA Facial Plastic Surgery, and Otology & Neurotology. Several of his publications have become widely cited references in the field.

A Life of Adventure &
Physical Challenge

Outside the clinic, Dr. Keller is equally passionate about athletics and family. He shares his love of Colorado's natural landscape with his wife and two young sons, prioritizing outdoor adventures that keep the family active and connected—whether hiking mountain trails, camping under the stars, or skiing the slopes in winter.

As a dedicated endurance athlete, Dr. Keller regularly competes in triathlons and Ironman events, and has summited many of Colorado's famous 14,000-foot peaks (the "14ers"). This commitment to physical challenge mirrors his approach to medicine: disciplined, goal-oriented, and rooted in the belief that consistent dedication yields transformative results.

For Dr. Keller, staying active isn't just about personal fitness—it's about modeling a balanced, healthy lifestyle and deeply understanding the physical resilience his patients aspire to maintain in their own lives.
