Estela Koontz– Practice Administrator

Estela oversees patient relations, employee relations, practice accounting and administration. She also is interested in current technology and how it affects procedures today. Her entrepreneur spirit helps keep our practice up to date in the latest technology and current information related to patient care. Being a prior surgical assistant and sedation monitor has given Estela the unique appreciation of patient and doctor perspectives, how they relate to each other, and the procedure expectation.

Her message to patients is that we care, and we want them to be comfortable, open and honest. She wants to hear from them, whether their feedback is positive or negative. She is always interested in ways to improve the lives of our patients and how to best support their needs.

She traveled to many places around the globe before she decided to call Virginia home in 2009. Estela brought a wealth of experience in business administration, insurance and customer relations when she joined our practice. She also has a diversified background in business ownership and extensive experience in contract negotiations.

She enjoys reading about the latest studies and research on human issues, DNA research, pharmaceutical technology, and the expansion of computer technology.

Estela has three daughters with whom she loves spending time. Two of them have graduated from Cox High School and are in college.


Annette Haberdash– Dental Assistant

Annette has been a dental assistant in Virginia Beach since 1990, and she is gifted at making people feel comfortable. She enjoys the creative side of dentistry and how it transforms a person’s life by improving their smile. She has a background in design, photography, real estate and massage therapy.

Annette is an animal lover at heart and owns a boxer. When she isn’t improving smiles, she enjoys events with family, friends and her daughter, and she loves to travel. She also likes to walk on the beach, exercise, give massages, attend musical concerts, paint and bake.


Robin Combs– Dental Assistant

Robin graduated from the Leone School of Dental Technology in West Babylon, NY in 1986. She enjoys the limitless educational opportunities the dental field provides, which enable her to better provide for our patients.

A passion close to Robin’s heart is volunteering dental services at no charge for individuals who are unable to pursue care due to limited or no financial means.

Outside the office, Robin is dedicated to mentoring programs geared toward middle school students. These opportunities have allowed her to introduce and research future goals that can be met through studies, positive choices and hard work.

When she isn’t working, Robin likes camping all over Virginia with her husband, family and friends. Her ultimate goal is to relocate to Hawaii when she and her husband retire.
