About:

Kristine E. Barrett, DMD believes in comprehensive care. This involves not only addressing any immediate concerns patients may have, but also seeing the bigger long-term picture in a patient’s treatment plan. She is passionate not only about treating every patient with care, but also customizing plans as she understands everyone has different needs. Through her advanced training that goes beyond her DMD, she has worked with various specialists (oral surgeon, endodontist, periodontist, advanced general) to further her skills as a general dentist.

She enjoys staying healthy through various physical fitness routines like cycling, body combat, yoga, and HIIT. But she can also be quite a “foodie” when it comes to finding the best spots to eat or creating a delicious meal of her own in the kitchen. Her free time is mostly spent appreciating quality time with family and friends, playing with her new pup, and escaping to Disney World when given the opportunity.
