I feel every patient’s hearing loss, hearing needs, personal preferences and budgets are different. It is my job to teach you everything you need to know about your hearing loss and all possible solutions that may provide benefit to you. Technology alone doesn’t help people hear better—it is how well I work with you and how well I apply that latest technology. I will answer all your questions and make sure you understand your hearing devices to maximize your listening situations. I’ll make sure your hearing aids are comfortable, work properly, and provide the most benefit. Encouragement, guidance, patience and proper instruction are essential components through the duration of your hearing aid learning process.

“I take care of my patients with the personal touch that I would expect if I were the patient.”
