I met Andy and Leonard many years ago -- and was so impressed with them that despite the fact that I live in central Mexico and there is a Hearing Aid Center in a nearby city, I stop in Selma every year for my annual hearing test when I visit my family. Andy is extremely knowledgeable, incredibly calm and patient, and provides me with thoughtful analyses and recommendations. He alerted me to abnormalities that I needed to have addressed by an EENT physician prior to returning for new hearing instruments. He's the BESTperson in his field that I have ever experienced -- although he refuses to take complements personally, as he defers to his "Team". I have recommended every person I know to this particular Costco for their hearing aid needs. And last but not least, Leonard is incredibly efficient, also extremely kind and patient. He answers emails and calls quickly and completely, and keeps my instruments in perfect condition. Don't know what I'd do if they ever moved! Thank You!!!
