what we do

Our Staff

 Administrative Assistant / Coordinator

Hi my name is Theresa and I have worked in the dental field since 1986, and have been with Dr. DeVengencie since 2008.


I enjoy working here because we get to take care of people who are having pain and make them “smile” again.


My husband Derek and I live in Wellington with our son Devin. In my spare time I enjoy traveling, spending time with my family.

Certified Dental Assistant

Hi, my name is Katie. I have been a Dental Assistant since 2008. I have been a team member with Dr. DeVengencie and Endodontics Limited since 2011.


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!

Lead Dental Assistant

Hi, my name is Andrea. I have been a Dental Assistant since 2003 and I have been a part of Dr. Devengencie’s practice since 2013.


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.

Administrative Assistant/ Coordinator


Hi, my name is Jennifer. I have been working in dental administration since 2011. I am the newest member of this team and I'm incredibly lucky and proud to be here because every aspect of this practice offers a higher caliber experience for our patients.

My husband David and I have three children; Logan, Alex and Lyric. In the warm weather I enjoy disc golfing, camping, traveling and exploring waterfalls. We also like swimming, tubing down the river or spending time at the beach. In the colder weather I enjoy cooking and baking goodies for my loved ones. I love the fall, especially Halloween! When the snow starts to fly, we love to go sledding or you will catch us making snowmen or homemade snowlides in the front yard.
