Stephanie and her husband Chad have two young children, one girl and a new baby boy that keep them young and busy! In her spare time, she enjoys cooking, playing outside with her kids, and golfing with her husband, and doing home projects. Dr. Heyland went into dentistry because she loves working with people and wanted to combine her interest in healthcare and passion for arts. One of the main focuses of her dental education was cosmetic dentistry which she hopes to incorporate with some of the latest dental technologies in our practice.
Dr. Barbara Gipple
Dr. Barb Gipple has been practicing dentistry since 1989. She originally grew up right here in Southeast Iowa and graduated from the University of Iowa College of Dentistry in 1989. Dr. Gipple first became interested in dentistry because she wanted to work in the healthcare field, liked to work with her hands, and was looking for a way to use her art degree. Dentistry allowed her to incorporate all of these interests in caring for her patients, and she especially enjoys the esthetic aspect of dentistry. Barb is married to her husband Randy and stays busy outside the office with her 18-year-old twins. She loves to garden and to travel, and she typically serves on at least one international mission trip each year. Dr. Gipple’s patient care philosophy primarily stems from treating each patient as if they were a member of her own family.
Dr. Ronald Stein
Dr. Ronald Stein was born and raised in the Southeast Iowa area. After graduating high school he enlisted in the United States Air Force where he was stationed in Wethersfield, England, and married his wife, Susan, in Ireland, in 1966. On returning to the USA, in 1967, Dr. Stein first took up a position for Television and Radio Repair, in a local Keokuk store, and shortly after that, worked as a Prosthetic Technician. During his medical study for this new position, he gained a great interest in the dental field and his desire to help others maintain good dental health propelled him into the study of Dentistry at the University of Nebraska, where he graduated in 1976. After over 34 years of private practice, he was honored to join the team of Dr. Mark Pothitakis. In his private time, he supports and enjoys helping in his wife’s music distribution company and encouraging their two children and 8 grandchildren in their various positions in life.
