Tarah Ridenbark-Crews, D.M.D

Dr. Tarah Ridenbark-Crews is from the small town of Staunton, Illinois where she grew up on a farm raising various animals and growing crops. She has a wonderful, large family of two older brothers and two younger sisters. And she has recently been promoted to auntie! As a child, she enjoyed trips to the dentist and knew that’s what she wanted to do. She received her Associates of Applied Science from Lewis and Clark Community College, Bachelors of Science in Biology from Southern Illinois University Edwardsville, and her Doctorate of Dental Medicine from Southern Illinois University School of Dental Medicine.

During dental school, she was able to provide many hours of community service and education, and she continues to volunteer in the community to this day. She also had the opportunity to attend a mission trip to Jamaica, where dental care was provided to thousands of people in need. She intends to volunteer for more missions trips in the future. Dr. Ridenbark-Crews enjoyed following in the footsteps of Dr. Flavin by participating in the Give Kids A Smile organization.

Dr. Ridenbark-Crews exclaims, “What I like most about dentistry is the ability to communicate with and educate my patients about their dental health and improving their oral condition. I pride myself in being an accessible and personable professional, dedicated to the care of my patients. Dr. Flavin has been a wonderful mentor to me during my time at Healthy Smiles. Not only has he taught me about dentistry, but his compassion toward each and every patient has made a huge impact on how I practice dentistry. I intend to follow the same practice philosophy and treat each patient as family, just as he has done for many years.”

In her free time, she enjoys spending time with her family, reading, and traveling. She’s a big fan of the Harry Potter book series, Taylor Swift, and the St. Louis Blues. Most of all, she loves spending time with her dog, Doc, and husband, Tyler.
