Dr. Michael Flewelling

Dr. Mike Flewelling is proud to be your dentist. As a native of Michiana, Mike grew up in our community and understands the needs and concerns of his patients.

After graduating from Buchanan High School, Dr. Mike enlisted in the United States Marine Corps Reserve, where he faithfully served 7 years with Charlie Co. 1st Battalion 24th Marines stationed in Lansing.  In  2003 Company C was deployed to Iraq where Dr. served our Country honorably and was awarded a Certificate of Commendation in recognition of his leadership during the conflict.

After returning home, Dr. Mike set his sights on continuing his education.   He completed his undergraduate degree at Andrews University, where he received his B.S. in Biomedicine, and, more importantly, where he met his beautiful wife Tracy!  After graduation, Dr. Mike was accepted to the prestigious Loma Linda University School of Dentistry in Southern California.  There, he served as President of his class and helped to establish a class level peer review committee that helped ensure students received the assistance they needed with their studies.  Upon graduation Dr. Mike received multiple awards including the Prince award for leadership, which is the Dental Schools highest bestowed honor, and the Mountain award, which is the schools highest clinical honor, for his compassionate and ethical treatment of his patients.

After graduation Dr. Mike spent some time working as an associate dentist in a large Chicago clinic before returning home to southwest Michigan.  Dr. Mike and Tracy are very excited to be a part of the Niles community and near to family once again.

When not in the clinic, you may find Dr Mike on the golf course in the summer or on the snowmobile trails in the winter.  He also enjoys a lazy day at home with a good book and time with his family.  Dr Mike is an avid sports fan, and be forewarned, if you get him talking football your appointment may last longer then you thought!
