Cadan Kleinheksel, a board-certified hearing instrument specialist, brings both deep technical knowledge and a genuine, down-to-earth approach to patient care. He earned his Bachelor of Science in biology with a minor in kinesiology from Hope College, and has been immersed in the hearing care field since age 17—doing everything from cleaning the clinic to assisting with nursing home visits. His early hands-on experience and long-standing commitment to the profession laid the foundation for his passion today.
Cadan is known for blending science-based expertise with an open, honest communication style. He has a knack for breaking down complex hearing topics into easy-to-understand explanations and helping patients feel informed, empowered, and at ease. A true “hearing tech geek” at heart, Cadan is driven by a love for innovation and a deep belief in the power of accessible, caring healthcare.
"Cadan has an exceptional knowledge of hearing, hearing issues, and how to manipulate/fine-tune hearing aide devices. He is very friendly, easy to talk to and work with. He has improved my life by fine-tuning my hearing aides to the point where I firmly believe I can hear better than many of my friends & family members. Thank you!”

Dr. Terry R. DeGroot is a graduate of Wheaton College (Illinois) and the Michigan State University College of Human Medicine. His surgical internship was completed at Spectrum Health Butterworth Hospital in Grand Rapids, Michigan. He completed his residency in otolaryngology at the University of Rochester Medical Center in Rochester, NY. He was board certified by the American Board of Otolaryngology in 1980 and has practiced in West Michigan since that time.
Dr. DeGroot will be providing medical input and care for current and potential hearing instrument users in the Grand Haven and Zeeland offices. His services will include cerumen management and examination and treatment of ear canal and hearing concerns.
Dr. DeGroot says, “One of the joys of my practice over the years has been to become involved in the lives of patients from newborns to the very elderly, those with minor problems to life threatening issues. Assisting individuals to deal with ear and hearing concerns has been particularly rewarding as this area provides opportunity to dramatically improve the quality of lives of patients, their loved ones and their social circle. What could be more gratifying than aiding individuals in living better and happier lives on an every day basis.”
He resides in Grand Haven, with his wife, Sandi. They enjoy gardening, cooking and motorcycle riding.
