Meet the Administration Team


Insurance & Financial Coordinator

Hello! I’m Chris and I am the Financial Coordinator & one of the Treatment Coordinators here at Marble Hill, I have been in orthodontics for over 10 years. I have a mind for insurance and finances and a relaxed calming personality that makes most of our patients feel comfortable. I am here for you throughout your treatment from the first day you come in until the day you get your braces off!

Outside of the office you can most likely find me paddle boarding with my pup, biking, fishing, boating, hiking, walking on the sand bar, or scavenging for beach treasure – really the list is endless! I am obsessed with having fun, life is too short not to! In addition to having fun, I am a human mom to four amazing children (three boys and a girl), a fur mom to a springer spaniel (Lily), and a feather mom to a cockatiel.


Scheduling & Marketing Coordinator

Hi! My name is Bri! I am the Scheduling and Marketing Coordinator here at MHO! My favorite aspect of working in orthodontics is being able to help the patients & families here at Marble Hill since they are so kind and fun to be around! I graduated from Desales University with a Bachelor's Degree in Marketing and I can not be more excited to be able to put my marketing skills to use here at Marble Hill Ortho!

When I'm not at the office you can find me doing some of my favorite things like spending time with my fiancé, family, and our four pets. I have three cats named Lizzy, Millie, & Benji and a dog named Vinny (Dr. Vinny here at Marble Hill)! I also love to spend time relaxing and reading a good book! :) 

Meet the Clinic Team


Clinic Assistant, LRDA-O

Hello! I'm Karen one of the clinical assistants here at Marble Hill Orthodontics. I am a Licensed Registered Dental Assistant in Orthodontics and also have my New Jersey Dental Radiology License. I assist Dr. Walter and Dr. Alys with daily orthodontics procedures and work with the patients on a one-on-one. I have been part of the Marble Hill Family for many years! I love getting to know our patients! One of my favorite things about my job is how funny some of the patients are, they can have me laughing even when I get home at night. 

I love spending my time outside of work with my family which includes my husband, Don, my two daughters, Meghan and Morgan, and my son, Nick. I am also a huge Disney fan and visit Walt Disney World every chance I get!


Clinic Assistant, EFDA

Hello, I am Stacie. With over 30 years of dental and orthodontic experience, I am a Registered Dental Assistant with a X-ray and expanded function licenses. What I love about my career is making our patients feel special from their first appointment to the last. Their care is my priority and I strive to make them feel comfortable through their whole orthodontic experience. I love having fun with my patients and getting to know them throughout their treatment. Through my continuing education, I love to learn the latest techniques using our state of the art equipment here at Marble Hill.

Outside the office I enjoy many outdoor activities with my husband. We like to camp, kayak, hike and ride our motorcycles. From spring to fall in our we love to garden and also raise honeybees. I believe in making every day count, spending time with family & friends, creating lifelong memories.


Sterilization & Lab Technician

Hey everyone! Brittany here! I am the Sterilization & Lab Technician at Marble Hill Orthodontics. I hold a New Jersey Dental Radiology License and help with the day-to-day organization, restocking, patient flow, X-rays, Scans, and all lab procedures. It's been very exciting getting to  learn a new trade and having the opportunity to advance on the clinic side of Orthodontics! I am currently in the process of becoming a Registered Dental Assistant and look forward to what the future holds for me here at MHO!

In my free time, I love to nag my children (10 and 8 ) with cleaning and family chores, cooking recipes they won’t eat, and baking to insure they eat something. My husband and I keep from going insane with music of any kind, you suggest it, we will listen at least once. Looking forward to meeting you and welcoming you to the Marble Hill Ortho Family.
