Dr. Rachel E. Crittenden
Dr. Rachel Crittenden is excited to be part of Preservation Dental in Northville founded by Dr. William Demray. Her commitment to dentistry began in high school when she served as an intern “shadowing” Demray and learned firsthand what it takes to treat patients and run a dental practice. Preservation Dental has been providing cutting edge dental services delivered with personalized care to the southeastern Michigan community for 45 years. “Preservation Dental’s core values especially for children and families were the right fit for me and aligned with why I wanted to be a dentist,” said Crittenden. “Instead of a cookie cutter approach where all procedures fit all patients, this team is committed to customizing patient care.”
Another appealing aspect was Preservation long-standing tradition of giving back to the community. Demray and many of his staff serve on Boards, help with local fundraisers, and collaborate with the local Chamber of Commerce and other community leaders to better serve the lives of their neighbors and patients. During her high school internship, Crittenden also participated in community events including playing the role of “Miss Sweet Tooth” in a Northville Halloween parade.
Upon graduation from Northville High School, Crittenden attended the University of Michigan and received her bachelor’s degree in Biopsychology, Cognition and Neuroscience. She continued her education at the University of Michigan School of Dentistry and received her DDS (Doctor of Dental Surgery) degree.
During dental school, she served as vice president of the U of M chapter of the American Academy of Pediatric Dentistry and became interested in a general practice where she could provide services for both children and adults. She is affiliated with American Dental Association, Michigan Dental Association, as well as Delta Sigma Delta and Gamma Phi Beta sororities.

For as long as she remembers, Denise has enjoyed theater and is curently the President of the Tipping Point Theatre Board of Directors - but - her favorite role is ``Grammy`` to three wonderful grandchildren.
