Meet the Doctors

Dr. Joe Wertz attended the University of Iowa for his undergraduate studies and continued his education at the University of Iowa College of Dentistry where he graduated with his Doctor of Dental Surgery in 2010. Since graduation, Dr. Joe has continued his study of general dentistry through numerous continuing education courses every year. Dr. Joe’s commitment to dentistry continues with his memberships to the Iowa Dental Association, Dubuque Dental Society, American Dental Association, Academy of General Dentistry, Chicago Dental Society and Great River Implant Study Club.

Dr. Joe and his wife Moe settled in Dubuque in 2010 and he joined his father, Dr. Tom, and Uncle, Dr. Mike, at Wertz and Wertz Dental Associates. Dr. Joe became a partner at the practice in 2012.

Dr. Joe and his wife welcomed a new baby boy, August “Gus” Patrick Wertz, in late January 2015. When Dr. Joe is away from the office during the summer months, you can find him on the waterways of Iowa with his family and friends boating, tubing, skiing, jet skiing, fishing and generally spending time outdoors! In the winter months, Dr. Joe spends his time in his garage “wrenching” on his vintage stand-up jet skis, always attempting to get them running a little faster. While working on his jet skis, his motto is “if it is not broken, fix it until it is!”

Dr. Mark's wife, Chandler (Flynn), is a native of the Dubuque area and is an insurance broker at Cottingham and Butler in Dubuque. Mark and Chandler were married in June of 2017 and are excited to return to their hometown to be with family and spend time in the community that they have known and loved their whole lives.
