practice manager

Marlyn pacheco

I joined our team in 2013. 
I have been working in the dental field since 1991. In this time frame I have acquired a wide variety of experience in General and Specialty Dental Practices including: Endodontics, Periodontics, Oral Surgery and Implantology. I always look for ways to improve the care that our patients receive. I make it my first priority to make sure that all their questions and concerns are addressed in a timely manner. Endodontic procedures can be in some cases overwhelming and scary for a lot of our patients.   This is why at Root 66 Endodontics, we make sure that the overall experience of our patients is pleasant and comfortable, so at the end of their treatment  they can go home pain free and with a happy smile.
Our staff is very warm and inviting and I really appreciate the attentive care our doctors and team strive to provide as individuals and collectively for each patient. 
In my spare time I enjoy spending time with my family.  I love to travel and explore different experiences with my family and friends.

I’ve had the pleasure of being part of The Root 66 Endodontics team since December 2017. I am passionate about being a patient advocate. There is nothing more satisfying to me than to be able to help calm my patient’s fear of endodontic procedures. I enjoy answering all their treatment concerns and to help them clarify all their Insurance benefits questions.

Lisette joined our team in 2013

Working in the dental field was never in my thought in the past, but since joining the team at Root 66 Endodontics, it has really opened my eyes to a whole new world.  I joined this field with little experience, but learned a lot with in a couple of months with the help of all the staff including Dr. Halpern. Every patient is different and unique in their own way. Every case is different and no day is the same which makes for an exciting work environment. I love when our patients leave with a smile on their faces because they are no longer in pain due to our hard work and dedication to each individual. You could call us superheroes!

In my spare time I enjoy spending time with my family and friends. I love being creative doing things such as: photography, arts and crafts and party planning.
