To our valued patients and referring physicians, 

We are happy to announce the merger between Los Angeles Ear, Nose & Throat Associates (LA ENT) and Los Angeles Center for Ear, Nose, Throat and Allergy (LA CENTA). 

Beginning on November 1, 2017 LA ENT Associates will be working under the umbrella of Los Angeles Center for Ear, Nose, Throat and Allergy run by Dr. Geoffrey Trenkle. Dr. Richard Clark will continue practicing under the new partnership to help merge the two practices and help with the patient and referral transition. 

It brings us great comfort knowing that our patients are in good hands with providers that share the same dedication and attention to care that LA ENT Associates has strived to deliver throughout the years. Dr. Trenkle has built a reputation in the community of care and compassion towards his patients and is committed to developing a comprehensive ENT practice to help provide university-caliber care to the community.
LA CENTA is committed to serving patient’s needs with an expert team of ten providers that work tirelessly to offer all patients the highest quality of care possible. LA CENTA utilizes top-of-the-line equipment, excellent facilities, and the latest training techniques to address each patient’s needs.

The next few months will be a transitional period, and we apologize for any inconvenience this may cause. LA CENTA is working hard to limit any confusion and to help make the transition smooth for both physicians and patients. Our office will be undergoing renovations during the month of November. To avoid any lapse in care, patients can go to any of LA CENTA’s four other locations for treatment: East LA (323-268-6731), Glendale (818-553-8013), Hollywood (323-593-7682), or Monterey Park (323-593-7679).
