Dr. Cassondra Braun

Dr. Cassondra Braun is excited to be joining Madison Family Dental and the Madison community! She grew up in Breckenridge, MN, with her parents and one younger brother. She became interested in dentistry at a young age by visiting her mother, a dental hygienist, at work. After high school, Dr. Braun attended the University of Minnesota for her undergraduate education where she graduated magna cum laude with a major in Biology. During her time there, she completed research in the Department of Genetics through the Undergraduate Research Opportunities Program and volunteered weekly at the University of Minnesota Masonic Children’s Hospital.

Dr. Braun received her Doctor of Dental Surgery degree from the University of Minnesota School of Dentistry. She is a member of the American Dental Association and the South Dakota Dental Association volunteers for Give Kids a Smile. Dr. Braun enjoys all aspects of dentistry but is particularly interested in pediatrics, oral surgery, fixed prosthodontics, and cosmetic cases.

“Dentistry is a wonderful profession that allows me to provide care for others while using my technical and artistic abilities to fulfill patients’ dental needs and desires.  In addition, the field is constantly changing which makes every day very exciting. While I enjoy the clinical aspects of dentistry, I receive the most joy when I am able to make a patient's time in the dental office a positive light in their day. I am thrilled to join the talented team at Madison Family Dental!”

In her spare time, Dr. Braun enjoys spending time with her family and friends, cooking, playing the piano, fishing, snowmobiling, camping, traveling, and being walked by her English Bulldog, Henry.
