Tammy RDH - Hygiene Team Leader: "It has been a great opportunity to work over half of my 20+ years as a dental hygienist at Chatham Dental Center. We have so many wonderful patients that I look forward to seeing each and every day. When not at work, I enjoy spending time with my husband and two children. Their various sports and church activities keep us busy. When I do have extra time I like to go running, spend time in the garden and relax at our family cabin."
