As a Bergen County native, I am knowledgeable about Northern NJ, the opportunities it provides to individuals and families and look forward to helping others find their home or investments. I am committed to helping my clients find a community and home that meets their needs, whatever those may be.
At a young age, I shadowed my father who was immersed in the world of real estate, both commercial and residential, which sparked an interest in me. After graduating with a business degree from St. Thomas Aquinas, I decided to work alongside my family. Managing a family-owned business for the last 20 years, I've developed a strong work ethic, good communication skills and forged lasting relationships with clients and companies. I value the connections I make–both professionally and personally.
I enjoy spending my free time with family and friends and home improvement projects. My wife, two children and I enjoy spending time outdoors, exploring new places and movie nights at home.
