Meet Mid-Columbia Dentists

Dr. Reggie Orozco headshot

Dr. Reggie Orozco

Dr. Reggie Orozco is beloved by patients across all the Tri-Cities. Having grown up in Mesa and Pasco, people gravitate to him for his charm, wit, but most importantly his gentle care! He is an active participant in the prestigious Seattle Study Club. You are able to see the dentist that other dentists throughout the state of Washington look up to, right here in the Tri-Cities!

Dr. Spencer Greer headshot

Dr. Spencer Greer

Dr. Spencer Greer is an award-winning dentist and authority in implant dentistry and is certified in conscious sedation dentistry. Woohoo! And in his free time he enjoys golfing, eating donuts, falling asleep 20 minutes into every movie, and playing family soccer and duck-duck-goose with his wife and 5 kids! Patients love coming to "the singing dentist" that just can't shake tunes out of his head! Watch out when a Beatles song starts playing in the office.

High quality dental care for you and your family
