Dr. Cristea’s Biography

Dr. Cristea believes in a proactive approach to dentistry. Preventing an issue before it appears or treating it while it is still a minor one saves the patient time, energy, and money. Working at Willamette Dental appeals to her because she enjoys the interaction with general dentists and other specialists. Some cases require a lot of interactive specialty work and having all the specialists in the same office makes it easier and more predictable for her and her patients. She also makes sure patients know they can reach her with any questions or concerns.

Dr. Cristea is a self-proclaimed city girl who loves swimming, skiing, and mountaineering.

I ALWAYS ALWAYS LOVE seeing Dr Cristea! She is the best Dentist that I've ever seen, to the point where I get excited knowing that it's her that I'll be seeing, I don't even mind that she'll be poking around in my mouth which I hate but she's so quick that I can get through it. Her and I always have a great conversation when she's done. I hope that I spelled her name right ??
