David Strange, DDS, MS
Dr. David Strange has lived in Colorado since 1977. He attended grade school and high school on the "west" side of town and graduated from the University of Colorado at Boulder. The foothills of Golden and the flatirons of Boulder are truly home to him. When he isn't in the offices playing with the children, a privilege he tries to convince the rest of us is actually work, you can find him on the slopes of Copper Mountain or at a crowded Folsom stadium watching his beloved Colorado Buffaloes.
Dr. Strange and his wife, Erin, live in Golden with their three children, Clara, Marshall and Sullivan. Clara loves to dance competitively, and play golf; Marshall loves to play football, baseball, golf, soccer, and basketball; and Sullivan competes in the the same sports his older brother does. The three kids enjoy skiing and snowboarding whenever the dance and sports schedules allow. The family is active in the children's school, extracurricular activities and church. They also love to travel as much as having three active children will allow.
Dr. Strange graduated from the University of Colorado at Boulder in 1994 with a BS degree in biology and the University of Colorado School of Dentistry in 1998 with the DDS degree. He then completed the Pediatric Dental Residency Program at Baylor College of Dentistry in Dallas, Texas where he earned the degree of Master of Science in 2000. His master's thesis was on the subject of "Primary Tooth Pulp Therapy."
Dr. Strange has very fond memories of going to work with his father, who was a strong influence in his life. Following in his father's footsteps to become a pediatric dentist was a natural decision for him. It was a decision on which he has never looked back. Dr. Strange joined the Pediatric Dental Group of Colorado in 2000 after completing his pediatric dental specialty training. He practices in all of the offices but is known to schedule himself in the Frisco office on Friday to conveniently turn that trip into a ski weekend.
