Our Doctors


Dr. Stephanie Altenburg

Dr. Stephanie Altenburg has been a part of the Barry Road Dental Group practice for more than 30 years. She was the dental assistant and eventually an associate of the practice’s previous owner. She and Dr. Tim Altenburg purchased the practice in 2004.

Dr. Stephanie is a life-long resident of Kansas City, Missouri. A Park Hill High School alumni, she is a graduate of the University of Missouri-Kansas City School of Dentistry.

While she enjoys all aspects of dentistry, Dr. Stephanie’s passion is her cosmetic work, taking broken smiles that people are embarrassed of and want to hide, and giving them a healthy, happy smile they’ll be proud of.

“They just can’t stop smiling,” says Dr. Stephanie. “It is gratifying.”
