GC Realty and Development

CareersGC Realty and Development, LLC was originally founded by John Chiariello & Mark Ainley in 2003. It began as strictly a brokerage company, helping buyers and sellers with their properties, and developed into a full-service real estate brokerage offering sales, leasing, management, development, and investment properties. The first location was out of their home and the company totaled 2 people, John and Mark.

Today, GC Realty and Development, LLC employs dozens of people. Besides brokerage and management, the company works with scores of lenders, provides real estate education, and has been involved in thousands of real estate transactions.

Who We Are


Since its inception in 2003, GC Realty & Development was built as a family of individuals brought together for the purpose of bettering the lives of our community, doing right by our employees, and doing right by those we serve. Founders Bryan Sonn and Mark Ainley were brought together by the tragic loss of co-founder and friend John Chiariello, and built GCR&D to reflect their collective values and to carry on his legacy. We bring individuals into this company who share our common beliefs and thus have created an organization striving for excellence and positive recognition. We do not need to be the largest real estate company, but we seek to be the best.  

All members of GCR&D are committed to the highest standard of care regarding their job duties. Care and accountability involve the process of seeing it, owning it, solving it, and doing it. We do not push blame onto others, and when we say it will get done, we get it done in a timely manner and with the utmost diligence. Our work is as close to perfect as our abilities and capacity will allow, and we make every effort to mind all details within every aspect of our work. We keep our work organized so that customers and clients receive our full attention and their needs are completely addressed. 

GCR&D has succeeded and grown because of our mutual respect for one another, our customers, and our clients. We hold all employees to high levels of professionalism both within the office setting and within our daily lives, and expect all interactions to reflect this standard. Our dedication to this company and to hard work focuses our team, and ensures only the highest quality product and service possible in our industry is delivered. True quality comes from an overall attitude and we believe in leading by the example set by our founders.
