Our Team
We at Sentry are proud to have been servicing Northern New Jersey for over 47 years. Sentry has always been a family owned and operated business. Our goal and focus has always been to deliver prompt, reliable, courteous service at a fair and competitive price.
Our team is led by Jan TenHoeve with over 45 years’ experience in the pest control field. Jan has a broad knowledge not only of termites, carpenter ants, general insects and rodents but of structural damage repair and construction. He leads his team of well-trained, licensed technicians as well as helping all clients not only with experience but with respect and true caring. He is a past president of the New Jersey Pest Management Association and a long standing member of the National Pest Management Association as well.
JoAnn TenHoeve leads our office with years of experience and a knack of knowing many of our clients as friends that she truly cares about. She cheerfully answers the phone always looking to offer knowledge, help clients deal with pest control problems and scheduling not only as quickly as possible but for what’s most convenient for our clients. She is assisted by Mary O’Neill and Donna Dunleavy who are the best at keeping our office up and running smoothly.
Rich TenHoeve son #1 and our lead technician also has over 35 years of pest control experience and wonderful rapport with clients to whom he is well known and welcomed routinely.
John Bergin our highly trained and second technician, Ray Grimes, our trusted senior citizen who services all our Sentricon Termite Stations and Greg TenHoeve our technical training and entomology specialist round out our well trained, experienced and dedicated technicians.
We are truly proud of our “Sentry Family” and than each and every one of them for their dedication doing a great job and the many years they’ve been with Sentry.
