About the Team

Treby-Registered Dental Hygienist

We are excited to welcome Treby back as a returning member of our team. She was called away to Hawaii in 2010 to care for her husband who was hit with an IED while deployed to Afghanistan. 

She earned her Associate Degree in Science from Tri-State Business Institute’s Dental Hygiene Program in 2009 with the recognition of "excellence in dental hygiene education." 

What she loves about dentistry and working in our office in particular, is the high level of care Dr. Marks delivers.  She also values the ample time the practice allows her to spend serving each patient and educating them about prevention and good oral hygiene. Because prevention plays a vital role in overall health, she enjoys their return visits to her chair, with great checkups, caring about their oral health as much as we do.


Nelson, Registered Dental Hygienist

Nelson earned his BS in biology from Wheaton College and his AS in dental health from Luzerne Community College, where he was recognized as the outstanding graduate. His professional associations include Sigma Phi Alpha – Dental Hygiene Honors and Sigma Chi - Research Society.

While caring for our patients over the past twelve years, Nelson has loved the overall commitment to excellence shown by all members of the team. He works to maintain high standards.


Lisa, Treatment Coordinator

Lisa was educated at the Harrisburg Institute of Radiology and the West Branch Technology Center. She is a highly knowledgeable resource for patients in need of informative, easy to understand treatment planning and financing options. Lisa loves seeing our patients pleased with treatment results. She especially enjoys when someone smiles more freely after their teeth are cosmetically improved. Appreciative of the care our entire staff exhibits, Lisa looks forward to addressing any patient's needs and concerns.

In her free time, Lisa likes reading, hiking, water sports, attending craft shows, and being with her family. She and her husband have been married since 1986 and have two wonderful sons.


Kristan, Office coordinator

Kristen holds an associate degree in diagnostic medical sonography, and she joined our team in 2009. She has the important job of reminding our patients about regular cleanings and checkups, preventive appointments that ensure optimal oral health. An enthusiastic people-person, Kristen loves meeting new patients and maintaining relationships with existing patients.

When she's not working in our front office, Kristen enjoys playing with her children, Christian and Gunner, as well as watching their activities and antics.


Danielle, Treatment Coordinator

With nine years of experience in dentistry, Danielle joined our team in 2008. She works chairside with Dr. Marks to ensure that procedures run smoothly and patients feel comfortable during dental care. A lifelong learner, Danielle enjoys expanding her dental knowledge and sharing oral health information with our patients. She holds X-ray certification, so you'll probably meet her during your first visit. Danielle and her husband, Joe, have two beautiful daughters: Kyarra, age 13, and Katelyn, age 15. When she isn't transforming smiles with Dr. Marks, Danielle likes to watch her daughters' sporting events and spend quality time with her family.


Renee, Business Development Coordinator

Renee helped found the practice with Dr. Marks in 1973 and served the patients as a dental hygienist until 1990. She still is on loan to us when her teaching and consulting schedule permits. Currently she teaches dental hygiene and dental practice management at the Scottsdale Center for dentistry and in consults in the areas of periodontal care and practice management. She is a graduate of the University of Pittsburgh Dental Hygiene program and The Pennsylvania State University with a master's degree in training and development. She has lectured extensively throughout the U.S. and has articles published in professional journals.
