About Us

Our approach and philosophy to real estate, and business in general, is truly a part of who we are at our core. We named the company CastleArch to honor our parent’s immigration from two separate small towns in Italy in the late 1950’s – Castelgrande and Arce (pronounced ARCH-eh). Over sixty years later, their initial risk, sacrifice, and hard work, represents the foundation of all that we do for our clients.

“I have had the pleasure of working with Roberto since 2005. He is professional, diligent, and always open and honest. He always makes me feel like he is looking out for my interests. I would never do another real estate deal, whether purchasing or leasing without going to Roberto. Quite frankly, I don’t think anyone else could compare.”
