Dentist. Artist. Farmer. Father to two awesome kids, Alexandria and Ian. Husband to Maureen. Grateful son. Diehard Hokie and Philly fan. Skier. SSI Diver. Outdoor enthusiast.

‍Dr. Bydalek was raised in a military and artistic family and grew up travelling. Declining a scholarship to pursue an art degree in his senior year in high school, Dr. Bydalek decided to combine his artistic talent from his mom’s Dutch side of the family, and follow in his dad’s footsteps, a retired Air Force dentist, to pursue the field of dentistry where he felt he could use his skills to make the greatest impact.  

Dr. Bydalek obtained his undergrad at Temple University and then decided to remain at Temple for his doctorate at the Kornberg School of Dentistry. His passion in dentistry is cosmetic design because creating a new smile, or making a tooth that actually looks and functions like a tooth, takes time, talent and care to get it right. Staying on top of the latest advancements in dental care theory, technique and technology remains priority in his office and that is why he continues to invest in it. RiverValleyDental was the first practice in Hunterdon currently to offer Solea drill-less laser dentistry; in addition, the office has CEREC digital crown and implant dentistry, 3D Scan technology, Diagnodent laser cavity detection, and more.

Somewhere in throws of raising a family and beginning to really understand and value the necessity of proper nutrition, healthy lifestyle including enough sleep and exercise, Dr. Bydalek has decided to take on the current recommendation by the American Dental Association community to have a conversation with his patients with regard to their overall health and take ownership in playing a role in their overall care.

Dr. Andrew Tang was born and raised by hard-working immigrant parents, who taught him the value of hard work and service to others. Growing up in Freehold, New Jersey, Dr. Tang held an intense interest in science, pursuing a degree in biotechnology at Rutgers University. During college, he assisted his grandfather, a now-retired general dentist, and found that he loved dentistry’s unique blend of artistry and medicine.

A lifelong Scarlet Knight, Dr. Tang obtained his doctorate from the Rutgers School of Dental Medicine. During his time there, he was very involved in dental research and was recognized for his work as part of the ADA/Dentsply Sirona Clinician Research program, speaking at dental conferences across the US. Since graduation, he has completed a residency training program at Hackensack University Medical Center and has worked in public health for underserved communities.

Outside of dentistry, Dr. Tang loves spending time with his fiancé, Steph, and their affectionate dog, Cosmo. An avid musician, he spends his days off playing guitar and writing/mixing electronic music.

With the firm belief that advances in technology can make quality dental care more comfortable and more accessible to patients, Dr. Tang is ecstatic to join Dr. Bydalek and RiverValleyDental’s commitment to excellence.
