Dr. Tong & Lacap smiling family

Dr. Tong and Dr. LaCap first met in dental school at Columbia University School of Dental and Oral Surgery. In fact, they were anatomy lab partners. Was it love at first sight? You’ll have to ask them.

After over 19 years of working together as dentists, they still share the same passion for creating beautiful and healthy smiles. Their shared vision for Washington Dental Associates and Smile More Dentistry has materialized into an exceptional dental experience for their patients. Each is a unique dental office where you will feel comfortable, well taken care of and safe.

Another passion they share together is their love for each other and their five children. Their weekends are spent watching their sons’ soccer or baseball games - they have never missed one yet. When they are not in the office working, you can find them on the slopes skiing or the Hudson River boating.

Timothy MacLaga, DDS

Bergenfield Dentist, Dr. Maclaga

Dr. Timothy MacLaga has always wanted to be a dentist since the age 7 when he “extracted” his first tooth (on himself, of course—he did not yet have a license). His passion for dentistry shows in his enthusiasm, thoroughness, and gentle touch. His patients know that they will be well cared for.

When Dr. MacLaga is not improving the dental health of those around him, he occupies his time with a multitude of hobbies. He is a jack of all trade and master of many. He is a true Renaissance man. When you are in the office, ask him about the beer he is brewing in his backyard or the meal he will be preparing for his lovely wife, Jenna. He is most famous for his outrageous award-winning Halloween costumes! Come by around Halloween and see what he comes up with next.

He attended the University of Delaware for a Biological Science degree and a minor in Chemistry. He then went on to the University of Medicine and Dentistry of New Jersey to fulfill his lifelong dream of becoming a dentist. He completed his General Practice Residency at Woodhull Hospital in Brooklyn, where he became proficient in extractions and endodontics.

Nancy Gergis, DDS

Tappan Dentist, Dr. Gergis

Dr. Nancy Gergis graduated in 2001, obtaining her BDS degree from one of the top Schools of Dentistry in the Middle East. After working a short time at her Family Dental Center with both parents and her brother in the Middle East, she was selected to complete a multi-disciplinary hospital residency at Alexandria Research Dental Center ARDC. This residency provided her with advanced training in all the specialties of dentistry including treatment of medically compromised patients.

Dr. Gergis then moved to the United States and worked as a Dental instructor for dental assistants, then decided to have her second degree as DDS from New York University College of Dentistry. After graduation she immediately started to work as an associate dentist and currently at the Washington Dental Associates. Dr. Gergis is a member of the American Dental Association ADA and the New Jersey Dental Association NJDA.

Dr. Gergis' diverse background has given her a better understanding of our patients, their fears and their treatment. Patients often come to our office feeling anxious about their dental visit from previous experiences, but with confidence she eases those fears and provides gentle and an advanced dental experience. She enjoys the challenge of providing family dentistry in a comfortable, friendly and pleasant environment.

Dr. Gergis is heavily involved with the raising of her two children. They all enjoy traveling and doing outdoor activities.

Washington dental Associates is just a wonderful and ideal environment to provide dentistry at an exceptionally high level."
