Jeffrey King


Jeffrey earned his Bachelor of Arts in Communication Studies and Disorders from St. Cloud State University before pursuing his Doctorate of Audiology from Central Michigan University. Jeffrey enjoys spending time with friends and family, hunting, fishing, and golf. Why Audiology: Jeffrey always knew that he wanted to help others in life. He was unsure how he would do this until he took his first communication disorders course during undergraduate studies. After initially pursuing speech language pathology, Jeffrey discovered that his true passion was audiology. His goal is to improve the quality of life of patients and their family members by providing excellent hearing healthcare.


Christine Heintskill


Christine earned her Bachelor of Applied Arts in Communication Disorders from Central Michigan University and proceeded to also earn her Doctorate of Audiology from Central Michigan University. Christine enjoys spending time with friends, family and pets, hiking and camping, sewing. Christine discovered audiology through studying speech language pathology. However, after job shadowing an audiologist during a clinical placement, she realized that she had true passion for audiology. She had then decided that she would continue her education in audiology instead of speech language pathology.


Marlys Ebaugh


Marlys earned her Master’s degree in Speech and Hearing Sciences from Washington State University. She enjoys spending time with her grandkids, knitting, gardening, and reading. Marlys’ interests in communication and learning disabilities led to a long and successful career in Educational Audiology. She worked primarily with babies and children in North Iowa for over 25 years. Marlys found great satisfaction in removing obstacles that prevented a child from having a successful education and improved overall well-being. She has always had an excellent working relationship with Hearing Associates while working at the AEA (Area Education Agency). That relationship allowed Marlys and her team to provide the best of services to children with hearing aids in the schools. Because of the respect gained in partnering with Hearing Associates over the years and her continued commitment to helping others achieve better hearing, Marlys has decided to come on staff to work primarily with ENT (Ear, Nose, and Throat) patients.

“Rachael is my original person to see although when I go in as a walk-in I may see any of the staff. I trusted & enjoyed Rachael from the start, but no matter who I see I am always happy with how quickly I am seen and how promptly my issue is taken care of. I would not go anywhere else for my hearing aids!”
