Katie - Certified Dental Assistant


Hi, My name is Katie. I have been a Dental Assistant for 8 years. I have been a team member with Dr. DeVengencie and Endodontics Limited for 5 of those years. The best part about my job is the flexibility and work-life balance I’m afforded along with my amazing co-workers. I also love helping our patients and it is such a rewarding feeling when a person comes in with pain and then they leave our office knowing they received awesome service and they’re feeling so much better. I enjoy educating our patients about the process of their root canal treatment and explaining that it’s really just a fancy filling and that it is quick and painless. In my free time I enjoy life with my 3 kids. We enjoy going to parks and the zoo. My daughter also just started horseback riding lessons and she is a natural at it. I can be there when she needs me thanks to the incredible team at Endodontics Limited!

Alicia - Certified Dental Assistant


Hi there my name is Alicia! I have been a Dental Assistant for 3 years and currently have worked at Endodontics Limited for 2 years. What I enjoy about being a dental assistant is seeing a patient leave with a pleasant smile as they leave our office. To calm fears, answer questions and help make treatment possible, especially in a soothing environment is rewarding to me . Most importantly what I enjoy in the dental field is always learning something new! When I'm not working I enjoy spending most of my time outside with friends and family such as enjoying a nice walk in the Metro Parks, camping, fishing, and snowboarding/skiing when weather permits. I also enjoy painting canvases and crafting in my free time as well.

Andrea -Lead Dental Assistant


Hi, my name is Andrea. I have been a Dental Assistant for the past 14 years and I have been a part of Dr.Devengencie’s practice for the last 4 years. As a Dental Assistant at Endodontics Limited I am able to help patients feel confident about the procedure. I take pride in knowing I've helped transform even the most anxious, nervous and fearful patients into patients that still may not LIKE going to the dentist... but can get through an appointment simply by trusting that I will be there for them... I have to say, I'm proud to be part of a dental team that puts our patients first from the moment they walk in the door. We are here to welcome them with a warm smile, be aware of the importance of their time and get them in and out of their scheduled appointments in a timely manner. When I am not working I spend a majority of my time with, my 3 kids. I enjoy spending time with my family and close friends hosting game night and BBQ. I also enjoy going out dancing and working out doing Zumba.
