Dr. Theresa Tucker  DDS


Theresa Tucker is a General Dentist and has practiced in Klamath Falls for nearly five years. She was born and raised in rural Oregon near Silverton. The daughter of a grass seed farmer, she grew up working in all manners on the farm. She is the youngest of a very tight knit family of eight and is still very close with her siblings. Theresa attended Oregon State University in Corvallis, and received her Doctorate from Creighton University in Omaha, Nebraska.

When not working, Theresa can usually be found with her husband, Tyler, and her two Golden Retrievers. She is drawn to Southern Oregon because of her love of the outdoors, and whether she’s biking or skiing in the mountains, or running road and trail races, she always has a smile on her face.
