“Very professional, not sales people, will give you the help you need. My hearing aid is the best I've ever had, from 13 years old to now, I'm 73 years old!! Marcy O'Brien is a Dr. of Audiology, not a sales person. She was recommended by a nurse. God bless them both. I can hear better than ever before!! Talk to my family, they'll tell you, I can hear! I have a bad hearing loss. Call me, I can't recommend them enough! The best! ”
