Hello, my name is Courtney Wivell. I am the newest member of the Sierra Study Club, and have taken on the role as treasurer. I have been in the dental field for 6 years working for Dr. Jeff Berger. I started out as a dental assistant, went on to receive my RDA license, and most recently took on the role of Hygiene Coordinator.

Hello, my name is Jerusha Waelty! I have been performing the role of treasurer for the Sierra Study Club for several years now. I graduated in 2005 from University of the Pacific with my Bachelors in Dental Hygiene. After spending 3 years doing clinic work, I moved into the private sector working for Dr. Jeffery Smith, and still am practicing there today. My husband is the art teacher, and assistant cross-country coach at Bret Harte High School. Both my husband and I are local to the area, and look forward to raising our son, Emmett, here as well.

Christine Ojeda
RDH

I am the newest addition to join these wonderful ladies of the Sierra Study Club. I received my first introduction to dentistry in 2008 as a dental assistant in my hometown of Groveland. Two years later I was accepted into the Dental Hygiene program at Cabrillo College, and graduated in 2012. After graduating, I returned home to Tuolumne County to be close to my family. I am currently working 4 days a week at 3 different dental offices here in town. When I am not hopping from office to office, I love spending time with my family, my boyfriend Dan, friends, and my cat Sophie. I love where I live and try to spend as much time outdoors either snowboarding or hiking. I am lucky that I get to work with many amazing dental professionals and now I am happy and excited to be a part of this Club and help bring Continuing Education Courses local.
