5.0 star rating   2/28/2019   First of all id like to thank the front office Staff . Talk about great customer service . They actually listen to you and genuinely care about your day to day life ... the intake system they have in place is a beautifully orchestrated flow that gets you to the back patient room within minutes.  Secondly the billing Department, everything from managing insurance and giving me advice on how to handle my current financial situation was unique and exceeded my expectations by far. They are fair and very friendly .  Finally But definitely not the least , the Man himself , Dr. David Levin. His strong and confident presence not only makes you feel comfortable in every way but you can't help to hang on every word he says to you about your diagnosis. He is very thorough and by far the most intelligent man in his field .  I was having issues with the back inner section of my mouth and throat... he created a game plan and a structured lifestyle change that Included key over the counter Medicine and an important Diet change . I've followed his advice to the "T" and have had no issues whatsoever .. I highly recommend him!! Thank you Dr. Levin to you and your wonderful Team!!!

Professional Statement


Dr. David Levin is  a concerned and mindful ear, nose & throat doctor caring for (patients in San Luis Obispo, CA). He earned his medical degree from the University of Texas, San Antonio. He completed an internship in general surgery and a residency in otolaryngology at Los Angeles County+University of Southern California Medical Center. He also holds a bachelor's degree from Emory University. Dr. Levin is certified by the American Board of Otolaryngology and is a member of the American Academy of Otolaryngology – Head and Neck Surgery. Dr. Levin is devoted to ensuring the longevity of his patients’ health and developing long-lasting relationships with them. He takes his time to understand symptoms and give correct diagnoses to ensure the continued health of all his patients.

Dr. John McMahan recently moved to San Luis Obispo after many years at Northwestern University in Chicago where he sub-specialized in nasal, sinus, allergy, snoring and sleep apnea. He was a pioneer in endoscopic sinus surgery and has taught numerous post-graduate courses and served on a number of national and international scientific panels. 

After his residency he did a post-graduate fellowship in head & neck oncology – especially rare sinus cancers. He practiced in Utah (he is a skier) for years where cancer is rare but used his training to focus on sinus infections, nasal congestion and snoring and sleep apnea.

He was recruited by Northwestern to head their ENT Rhinology department and forged close relationships with the neurology, allergy, pulmonology, neurology, GI and sleep departments to collaborate with them as a team to address headaches, asthma, COPD, GERD and sleep issues. 

He has participated in medical mission work in Cuba and Moldova where he helped the ENT doctors there perform complex surgery and strengthen their endoscopic

surgery departments.

He loves nasal cosmetic and reconstructive surgery and complex endoscopic sinus surgery. He also evaluates and treats patients with snoring and sleep apnea.

He is one of the few certified divers Alert Network (DAN) ENT physicians in California specializing in the medical issues encountered by scuba divers – they have numerous ENT pressure-related issues.

He and Lynn have been married for 29 years and have four children and 9 (soon to be 10) grand children. They have a son and his family in LA and wanted to move closer to them and to escape the brutal Chicago weather. They love the California central coast… the weather, ocean and the kind, welcoming people here. 

He loves skiing, motorcycles and snowmobiles, skeet shooting.

He has always insisted on same-day appointments offered to all patients. Sinus sufferers hate waiting weeks or months to be seen. He brings this practice to San Luis Obispo which has proven wildly popular with our patients.
