Anupama Aranya
General Dentist

About Me

Dr. Aranya says, “I love that we are able to form lasting relations with patients even with the short amount of time we spend with them. I love to hear some of their stories as much as I enjoy doing their dental work and helping them maintain the best oral health possible. My dad is a dentist and I had watched him work since I was a kid. All the pretend playing had to get real one day!”

Ruben Alcazar

About Me

Dr. Alcazar says, “I consider myself fortunate to have the opportunity to work in a profession that is rewarding for both my patients and myself. The best part about being an orthodontist is building personal relationships with each patient and to witness how the patient’s overall attitude and confidence changes positively as we improve their smile during treatment.”

Dr. Alcazar is the son of a dentist himself. He earned his Dental Degree and his first Orthodontic Certificate in Peru where he is originally from. He earned his second Orthodontic Certificate from the Jacksonville University School of Orthodontics in Florida, where he also taught for 3 years before moving to the Pacific Northwest.

I enjoy spending time with my daughter and exploring all the outdoor activities that Oregon has to offer, like biking, hiking, kayaking, paddle boarding, windsurfing and camping–as well as traveling and discovering new places.”
