Meet Our Dental Providers

Theresa Collins, D.M.D.

General Dentist

Dr. Collins says, “The best parts about being a dentist is helping people, the variety of procedures and esthetic dentistry. I love working with people and watching someone’s self esteem greatly improve after their treatment is completed. I find the most rewarding cases to be patients who have a genuine interest in improving and maintaining their oral health.” She aims to create a welcoming and comforting environment by treating each of her patients like family.

After graduating from the University of Northern Colorado, Dr. Collins received her Dental Degree from the OHSU School of Dentistry. She’s a member of the American Dental Association, the Oregon Dental Association and the Academy of General Dentistry.

Dr. Collins says, “I spend my free time at the gym or outdoors, and love trying out all the wonderful restaurants in this city. I love the music scene in Portland. I also have a passion for nutrition, healthy cooking, and clean eating. I’m an Arizona native who fell in love with Portland while at OHSU. I’m a social butterfly that can make a mean strawberry rhubarb pie (homemade crust is key!), and am very close with my family.”
