John Grittner, DDS

Dr. John Grittner graduated from the University of MN with a biology degree, a minor in youth work, and a strong interest in child development.  These explorations lead him to the field of dentistry where he later attended the University of MN School of Dentistry and met Dr. Jadilyn Grittner.   Together they decided to move "up north" and he worked with The Red Lake Nation and with other Indian Health Service clinics.  These experiences helped him shape the doctor-patient relationship where utmost trust and integrity is necessary.  After returning to the Twin Cities, Dr. John spent the next few years focusing on family dentistry increasing his skills and scope of practice in St. Paul, a place where he and Dr. Jadilyn have chosen to live a raise a family of their own.  His overall goal is to create long-term relationships with his patients where all aspects of preventive and cosmetic dentistry can be incorporated into his patients' smile and oral health.  Dr. John is excited to start this next chapter in life with his wife Dr. Jadilyn and lead the team of Highgrove Dental Care.
