Colorado ENT & Allergy

The premier (and largest) ENT and Allergy & Asthma practice in the state of Colorado. Drs. Olson, Ernster, and Knox practiced on Cascade Avenue.

In 1995 the leading ear, nose, and throat physicians in Colorado Springs merged to become Colorado Otolaryngology Associates (COA). At that time, the practice was comprised of six physicians and four locations. Hohengarten, Pruitt, and Romett practiced at Carefree and Academy, near Penrose Community Hospital; and Drs. Initially, the practices maintained separate locations; however, in 2000, the practices combined into a single location in the Audubon Medical Campus at Union and Circle. That same year, Dr. Galloway joined the practice. In 2004, Dr. Wilcox joined COA, and, in 2006, two of the founding physicians of COA, Drs. Hohengarten and Olson, retired. Dr. Davis joined COA in 2007, and in 2008, to meet the increasing needs of a growing Colorado Springs, COA opened a second location in the NorthCare Pavillion adjacent to the St. Francis Medical Center at Woodmen and Powers. In 2011, COA merged with the Colorado Center for Otolaryngology to form Colorado ENT & Allergy (CENT&A). In 2014, Dr. Whinery joined CENT&A, and the practice now consists of 10 otolaryngologists/head & neck surgeons. Over 40 staff members ensure the effective operations of CENT&A, and its audiology services are provided by three audiologists and three audiology technicians.

Hearing changes often happen slowly, so many adults don’t notice them until conversations and daily routines become harder. Early hearing screening gives you a clear picture of your hearing health, helps catch concerns before they worsen, and can guide what steps to take next. If you’ve been asking others to repeat themselves or turned up device volumes more than usual, now is a good time to act.

Our Story

In 1995 the leading ear, nose, and throat doctors in Colorado Springs came together to form Colorado Otolaryngology Associates (COA). At that time, the practice was comprised of the following six doctors: Drs. Ernster, Hohengarten, Knox, Pruitt, Olson and Romett. Initially, the doctors practiced in a number of separate locations, but, in 2000, they combined into a single office in the Audubon Medical Campus at Union and Circle. That same year, Dr. Galloway joined the practice.

In 2006, two of the founding doctors of COA, Drs. Hohengarten and Olson, retired. Dr. Davis joined COA in 2007, and in 2008, to meet the increasing needs of a growing Colorado Springs, COA opened a second location in the NorthCare Pavilion adjacent to the St. Francis Medical Center at Woodmen and Powers.

In 2011, COA merged with Drs. Cichon, Smith, and Yohanan of the Colorado Center for Otolaryngology to form Colorado ENT & Allergy (CENT&A). In 2014, Dr. Whinery joined CENT&A, and in 2017 CENT&A and Drs. Baswell and Caplan of Colorado Springs Allergy & Asthma Clinic joined together. At the end of 2017, Dr. Romett retired, and Dr. Baswell retired in mid-2018. Dr. Keller joined the practice in the fall of 2018, and Dr. Yohanan retired at the end of the same year. The practice now consists of 9 ENT doctors, 1 Allergy & Asthma doctor, 1 nurse practitioner, 4 audiologists, and over 50 clinical and administrative staff members.
