Nicole Engelmann, DDS

Dr. Nicole Engelmann was born in Chicago, Illinois and moved to Clearwater, Florida at the age of three.

When beginning her undergraduate degree, Dr. Engelmann was a Studio Arts major due to her love of art and design. She enjoyed that she could still use her artistic side and love for science in dentistry and changed majors, graduating early with a BS in Biomedical Sciences and a minor in Film and New Media Studies from the University of South Florida in 2019. After falling in love with Ann Arbor’s history and an opportunity to experience all four seasons, she was ecstatic to accept an offer to attend the University of Michigan School of Dentistry. It was here that she met her fiancé, Matt, a native of Escanaba. After visiting his home and seeing the beauty of the Upper Peninsula, she always knew they’d eventually find their way back.


After graduating in 2024 with her DDS, Dr. Engelmann attended a 1-year AEGD program through Johnston Memorial Hospital in Abingdon, Virginia. She received specialist training in numerous advanced treatments including implant placement, root canals, and complex full-mouth rehabilitations. After two years in the mountains, she and Matt decided it was time to move back up north.

Dr. Engelmann is so happy to finally be back in Michigan close to family and friends, and looks forward to serving the amazing patients in the UP!
