Bio
As a Hanover, PA native and proud graduate of Hanover High School, I bring deep local knowledge and a genuine connection to the community I serve. With over 10 years of experience in retail sales, I’ve built a strong foundation in customer service, relationship-building, and results-driven strategies. My background has sharpened my expert negotiation skills, allowing me to advocate confidently for my clients and secure the best possible outcomes. Whether buying or selling, I’m committed to providing a smooth, informed, and client-focused real estate experience from start to finish. I am a graduate of York College, where I developed the foundation that supports my professional dedication and attention to detail.
Outside of real estate, family and community are at the heart of everything I do. I enjoy spending time with my wife and our two children, coaching youth baseball, playing golf, and cheering on my favorite teams as an avid sports fan. Whether you’re buying or selling, I’m committed to providing dependable guidance, hard work, and personalized service every step of the way.
