Nichole Harden

Dental Hygienist
Nichole moved to Northern Michigan at the age of 6. While attending South Maple Elementary School as a first grader, she came home from school and excitedly announced to her parents that when she grows up she’s going to clean people’s teeth. It seems a local dental hygienist had visited her class that day for National Children’s Dental Health Month, and Nichole was sold.

A 2012 graduate of Ferris State University, with an Associates of Applied Science, Nichole achieved her dream. A self-described type A personality, Nichole prides herself on patient education along with care and concern for her patient’s comfort and oral health needs. She is well versed in all areas of dentistry, ranging from restorative needs to periodontal disease.

In her spare time, Nichole enjoys spending time with family and friends; camping and boating in the summer months and snowmobiling in the winter. In May 2017 Nichole married her best friend, Curtis Harden. In September of 2019 Nichole and Curtis welcomed their first child, Rachel Olivia. Together, they share a strong devotion to family, friends and community. You can find them volunteering frequently at local school and community events, usually with other family members in tow.
