Dr. Whitney Forsythe, DMD


Dr. Whitney Forsythe is originally from a small town in Northeast Kansas (Wizard of Oz jokes are welcomed). She met her husband, Dr. Nick, while attending Midwestern University Dental School in Arizona, where a dental class barbecue turned into dating, which led to a marriage, and finally a joint dental practice! While she misses the sun and her family, she has absolutely fallen in love with the Pacific Northwest!
