Jarrett S. Grosdidier, DDS

Dr. Grosdidier aspired to be a dentist ever since he can remember. He grew up on a dairy farm in southeast Kansas, where he spent most of his time either working with his father and grandfather or practicing and playing sports. Although Dr. Grosdidier loved life on the farm, he knew that he wanted to become a dentist.

He attended Kansas State University on a football scholarship, enjoying his time playing tight end, and completed his Bachelor of Science degree in biology and pre-dentistry. Balancing grades and athletics took a lot of time and hard work, but Dr. Grosdidier succeeded with honors both on the field and off!

After graduating from Kansas State University in 1998, he attended UMKC School of Dentistry, where he was able to start pursuing his passion. He graduated in 2002 and has been practicing in the Kansas City area since. As a dentist, Dr. Grosdidier takes pride in taking the time to get to know each of his patients and their individual needs by using a conservative approach to dentistry. He enjoys serving the whole family. It allows the practice the opportunity to really get to know their patients. Patients are not just a number, and many of them go on to become lifelong friends.

Dr. Grosdidier is a credentialed Diplomate and active Board Member with the American Academy of Dental Sleep Medicine (AADSM) Annual Program Committee, a member of the American Dental Association (ADA), Kansas Dental Association (KDA), and Academy of General Dentistry (AGD). He maintains the dental clinic at the Kansas State School for the Blind in Kansas City Kansas. He believes that it is both a privilege and an honor to work with the students and the staff at this school.

Dr. Grosdidier and his wife, Kim, met in college and have been enjoying married life for more than 25 years. They have four daughters: Brynn, Josie, Elise, and Ava. He is an incredible dad who devotes his life to his family. Spending time with his girls is his favorite pastime.
