Meet Our Team

Jay Hapka, Au.D.
Doctor of Audiology
Dr. Jay’s top priority is to understand each patients’ motivations and goals through relaxed conversation. With many reasons to decide to take action on your hearing health, he wants to know what yours are. The questions and answers exchanged on the way to finding these reasons are important. They help Dr. Jay explain the patient’s hearing ability in a way that has meaning, as well as finding the best solution.
He has always loved working with technology but knew he wanted to make a difference by working with people. With Audiology at the intersection of healthcare and technology, Dr. Jay develops personal connections with his patients while using technology to empower them to change their lives.
Dr. Jay is excited to be back in his home state of Minnesota after being in Arizona, where he earned his doctorate degree from Arizona State University. There he was also a part of hearing health missions to Mexico and Africa. He received his bachelor’s degree in Speech-Language-Hearing Science with minors in Neuroscience and Spanish from the University of Minnesota – Twin Cities.
Outside of work, Dr. Jay loves to cook. His specialties are traditional sourdough bread and French Onion soup. (He’s happy to share and exchange recipes!) In the summer, he can usually be found around a barbeque pit. Now that he is back in MN, he looks to spend time fishing and snowmobiling.
