“I recently accompanied someone to Happy Ears Hearing Center for multiple tests and the experience was great for both of us! The person I was with felt completely comfortable right away thanks to the wonderful staff. Dr. Mortensen explained everything to me as well as the patient, and I learned quite a lot. Hearing loss is a difficult subject to talk about and it's even more difficult to take action. If you struggle with any auditory difficulties, I would highly recommend visiting Happy Ears Hearing Center so you can start living your life Happily.”

“I haven't been able to hear for 3 years with my current hearing aids. I went to see Dr. Mortensen because a friend told me she was wonderful. She programmed my hearing aids and I immediately noticed a difference. I can actually hear again. I highly recommend this doctor. ”
