  • Dr. Tim Blackiston, DMD

  • Joni Church

    OFFICE MANAGER

    I graduated high school in May of 2007 and immediately started my dental assisting program in the fall of the same year. I have been with Lookout Valley Dental since 2010. I was an assistant from 2010 until 2016 when I became the office manager. I still assist from time to time. My favorite part of dentistry is the relationships made with patients along the way. In my free time I enjoy watching my daughter play sports, walks with my dog through the neighborhood and spending time with my family and friends.

    REGISTERED DENTAL HYGIENIST

    I was born and raised in Mid Michigan. My family and I moved here the summer of 2014 making it almost 10 years I’ve spent in Tennessee. I graduated with my associates degree from Cleveland State and then moved out to Nashville to attending Remington College. There I got my certificate to be a dental assistant and decided to continue my education and became a dental hygienist. Once I was finished with school, I moved back to Chattanooga to be closer to family again. As a dental professional I enjoy interacting with people and in my personal life I enjoy being outdoors exploring Tennessee.
