William Castel grew up in Ridgefield, NJ. He was the oldest of three sons of Dorothy and William Castel. His dad was a Construction Electrician and in the early years and his mom was a devoted housewife and mom…They were both big sports fans, especially baseball as from a very early age they taught their sons how to play baseball and to “work hard at whatever you do”. Dad coached William and his brother Kenny’s Little League Baseball Team to three straight championship seasons

William developed a love for basketball as he approached Middle School years and spent countless hours practicing and developing his skills. He went on to have a very good HS career in both basketball and baseball and was awarded the Annual Brian Piccolo Award. He was chosen to participate and represent Bergen County in the Bergen County vs Hudson County HS Basketball All-Star Game. William had the opportunity to play College Basketball for Ramapo College as he was recruited by them and a couple of other schools, but at the last minute decided not to play and chose to work at Shoprite and coach a Recreation Basketball Team in Ridgefield while attending college. He earned a BS Degree in Education from Montclair State University and he eventually earned a MA Degree in Administration from New Jersey City University. It was the coaching that led him to a 25-year career as a Teacher and Basketball Coach!

William met his fiancée, Patricia, 15 years ago and have been together ever since and lived in Paramus, New Jersey along with Patricia’s three children Jennifer, Alexis, and Jimmy. William considers them his stepchildren. Seeing the children grow up and to be successful and responsible young adults has brought both Patricia and William much joy. It is the love and support from Patricia and family which has enriched William’s life and being present for Alexis’s marriage to Rich on September 30, 2017, and then the recent birth of their daughter, Samantha, have been some great moments. Yes, Patricia and William love being grandparents!

William Castel – Paramus Realtor & Author



Bill was an absolute pleasure to work with during the sale of my mother’s home. It was a complicated and lengthy process that Bill handled with the utmost patience and care. He always had our best interests in mind and repeatedly went above and beyond the basics of the job, continuously offering assistance, completing document requests and facilitating meetings between Buyer, Seller, Lawyers, and Title Company. I highly recommend Bill to anyone looking to buy or sell a home…you will be in great hands!!

I highly recommend Bill Castel as a knowledgeable Realtor. I was under a time constraint to find a home and Bill was always available to adjust his professional, courteous schedule to assist me in finding the perfect home for my family. He even interrupted his Christmas morning with his family to show me a house and write up an offer that same day! He guided me through the process and went above and beyond to ensure the closing, inspections, mortgage…went through smoothly. At the closing, the Seller’s representative mentioned that “if it had not been for Bill’s communication to the selling Realtor, they would not have accepted the offer, and the house would have been sold to another buyer”! His involvement was critical to the purchase of my home and I can’t thank him enough!

Hi Bill,

We just wanted to write you a note to thank you for all your hard work and diligence in helping us with our Condo Sale in Edgewater. We appreciate your keeping us informed every step of the way, as well as your responsiveness and accessibility. Some Realtors would be content to just sit back, hoping to collect their commission at the end of the day without even rolling up their sleeves…This was the case with our previous Realtor before signing with you. You treated the sale of our small Condo with the same care as if it were a multi-million dollar transaction! So, thank you again for not giving up and fighting for us until the end!

William Castel was recently my broker for the sale of my mother’s house. During this difficult time for me as this was the house I grew up in, Mr. Castel displayed the outmost professionalism and efficiency, as well as compassion and a personal touch. Mr. Castel immediately put the house on the market followed by an aggressive and proactive campaign, including several Open Houses. He brought potential buyers almost immediately and we were in contract within 2 months with the closing following a month later. Mr. Castel’s hands-on approach from listing to closing is a true testament to his dedication and success. I highly recommend him! 

-D. Mulligan
