A passion to find answers and do it right.

In 1995, Dr. Collie Shaw founded Central Arkansas Ear, Nose, and Throat Clinic (CA-ENT) in Conway Arkansas. Over 20 years later, CA-ENT Clinic continues to provide comprehensive medical and surgical treatment to patients with diseases and disorders related to the ear, nose, and throat. Dr. Ralph Marrero joined CA-ENT in 2010; expanding the practice's reach and ability to treat more patients. Both doctors are board certified in otolaryngology. Dr. Marrero is also board certified in sleep medicine (one of only 3 ENT doctors in Arkansas).  Dr. Shaw and Dr. Marrero are dedicated to their profession; they actively participate in specialized otorhinolaryngology medical associations, conferences, and continuing education to keep up to date on the latest innovations in the field. Dr. Shaw, Dr. Marrero, and their staff are committed to providing patients with rapid access to medical treatment and services that are tailored to their individual needs.
