Dr. Geoffrey B. Trenkle is the CEO and founder of the Los Angeles Center for Ear, Nose, Throat and Allergy that provides special care in allergy, audiology, ear/otology, head and neck, nasal and sinus disorders, pediatric ENT, snoring and sleep apnea, thyroid and parathyroid surgery, and voice and swallowing disorders.


Dr. Trenkle is board certified in otolaryngology/facial plastic surgery from Michigan State University. He is a native of Southern California, who grew up in Redlands and attended medical school at Western University of Health Sciences, Pomona.


Dr. Trenkle moved to Michigan where he trained in otolaryngology and facial plastic surgery at Michigan State University through St. John Providence Health System. During his time in Michigan, he served both as chief intern in his first year and chief resident in his final year.


Dr. Trenkle trained with some of the most prestigious names in otolaryngology and has traveled across the country to learn from the best minds in pediatric otolaryngology (Dr. Robin Cotton), neuroethology (Dr. Seilesh Babu), laryngology (Dr. Clark Rosen) and head & neck surgery (Dr. Stephen Freeman). He has also won awards at national conferences for his research in neuroethology.

Since 2014, Dr. Trenkle has brought unmatched quality medical care to five LAENT locations in Los Angeles.


“My favorite procedure to perform is in-office balloon sinuplasty,” said Dr. Trenkle. ”This is a minimally invasive technique to perform sinus surgery within the office.”

Over the past five years, Dr. Trenkle spent time perfecting a process to make procedure more effective and simple for the patient.


“I am now the West Coast preceptor facility for the most state-of-the-art technique in minimally invasive sinus surgery called TruDi Navigation,” said Dr. Trenkle. “This is an image-guided technique that is cutting edge and the future of our field. I have trained over 20 physicians on how to use this technology and perfect their techniques.”


Dr. Trenkle prides himself on complete patient care and being in touch with his patients and their families. He comes from a long line of physicians and understands the need for a long-lasting relationship between patient and doctor.
