Dr. Shannon Norman-Kotre has been practicing in Ann Arbor as a dentist since 2002. She grew up in Grand Rapids, Michigan and came to Ann Arbor in 1991 to attend the University of Michigan. She is a two-time graduate of the U of M, earning first a B.A. in Psychology in 1995 and then her DDS from the School of Dentistry in 1999. She was a member of the Taft Society, a group of students who provided free dental care during Saturday clinics at the dental school. She was also the Vice-President of her dental class in their 4th year.

After graduation, Dr. Norman-Kotre worked part-time for two years with her father who was a dentist in Ada, Michigan at Norman Family Dentistry, and at a large group practice in Westland, Michigan. In 2002, she became the owner of her own dental practice in Ypsilanti. In 2005, she opened the doors to a new location for the practice in Ann Arbor and has been practicing there ever since. Then, in 2025, she made the decision to step back from the business of running a dental practice and passed the torch to Dr. DiRenzo. She is still very passionate about the field, and you can find her in the office on Mondays and Tuesdays.
