Meet The Team

Lisa S. Nelson

Office Manager

I am Dr. Shuff's Office Manager and have worked for him for over 25 years but have known him all my life - he is my older brother. Over the years I have enjoyed getting to know all of our patients and seeing the children grow into young adults. I have been married for 34 years and have 2 grown children and 3 grandchildren. I enjoy spending time with my family and friends.

Karen Mann

Registered Dental Assistant

Hi, I am Karen Mann and I am one of the Registered Dental Assistants in Dr. Shuff's office. After completing the Dental Assistant course at Loma Vista Adult Education, I was placed with Dr. Shuff for a 3 month internship. That was 24 years ago. I was raised in Concord and I still live there. I share a small house with one of my daughters, three grandchildren and 1 bathroom. We hope to add a dog in the mix soon.
