Dr. Thomas Wolff – DDS

Dr WolffOriginally from Minnesota, I did undergrad at California Lutheran University, then continued my studies at the University of Alaska Anchorage, before attending dental school at the University of Southern California.

After dental school, I moved to Colorado and I owned a large practice in Boulder for 9 years before finding my home at Greeley Dental Health. In my free time, I enjoy spending time with my family. We are all outdoor enthusiasts enjoying skiing, hiking, and all that Colorado has to offer. I keep in shape playing soccer and hockey.

I enjoy all aspects of dentistry, but I am most fulfilled by creating a better dental experience for my patients. I find that focusing on the patient’s experience and what I can do to make it more relaxing makes for more comfortable and efficient visits.

Dr. Keegan Waldo – DDS

Dr. Keegan Waldo

Raised in the mountains of northeastern Arizona, Dr. Keegan Waldo was the second of five boys born to a medical family. He grew up enjoying skiing and hiking on both his local ski mountain, as well as almost yearly in Steamboat Springs, Colorado. Keegan was a boy scout and played soccer for many years before switching to cross country. After graduating valedictorian at the local high school, Keegan went on to study at Gonzaga University. In Spokane, he fell in love with the Pacific Northwest and had many great experiences largely centered around his community outreach.

He graduated in 2012 with a Bachelor of Arts in Biology and a concentration in Entrepreneurial Leadership. Dr. Waldo was lucky enough to stay in the PNW while he attended the University of Washington School of Dentistry, graduating in 2016. During his time at UWSOD, he became a Seahawks fan, learned to make sushi, and formed a deep love of the Puget Sound area. He then spent a year pursuing an Advanced Education in General Dentistry, as part of the Northwest Dental Residency in Yakima.

His residency had a special focus on endodontics, orthodontics, and laser use in dentistry. As part of the Yakima Valley Farm Workers clinics, Dr. Waldo loved bringing care to an underserved population while improving his dental Spanish. After his time in Yakima, Keegan traveled back to the Puget Sound area where he joined a private practice and worked for nearly 5 years. Being based in Bremerton, Waldo enjoyed getting to know the ebbs and flows of Navy culture while enjoying the Kitsap Peninsula. Here Dr. Waldo was privileged with becoming a CEREC and Invisalign provider while also becoming involved with his local dental association and rotary club. Dr. Waldo is coming to Greeley after deciding he is sick of the rain and wants to get back to his roots. He will be moving to be closer to his family in Arizona and looks forward to all the adventure the Rockies have to offer.
