Co-Owner, Broker

Meet "The Negotiator"

Hi! I’m Susan McCallion, Sanibel resident, former non-profit executive, mother of four, and Broker and Principal of McCallion & McCallion Realty. Together with my husband, Jim, we started our practice on Sanibel Island in 2009, and have since opened doors as our own brokerage. 

Our love for Sanibel Island started more than 20 years ago when Jim proposed to me on the island. Living in Miami at the time, we vacationed on Sanibel for a number of years before packing up and becoming permanent Island residents in 2008. While in Miami, I led a large non-profit dropout prevention program, Communities in School of Miami (CIS), which had a major impact on area high school graduation rates and encouraged students to continue to college. As President and CEO of the organization, it was my privilege to help CIS grow from serving 140 high schoolers to more than 6,000 students overall with a budget over $3 million, 15 staff members, 40 full-time VISTA and AMERICORPS volunteers and 200+ non-paid volunteers. 

For me, this experience was life changing, memorable and beyond rewarding. From it, I learned that I am a skilled negotiator and have a creative mindset and talent for finding innovative solutions to challenges that arise. I’ve found that these skills, combined with my passion for helping others has led to my success as a Broker and Realtor® on the island. Coupled with Jim’s background in marketing and technology, our brokerage presents a unique offering to customers, who appreciate being more than just a “transaction” in our books. We work hard to make sure our customers become acclimated with the island, and we serve as a resource even after they purchase their dream home. 


Originally from Manchester, Connecticut, I became a South Florida resident more than 25 years ago upon graduating from UCONN - #GoHuskies! Growing up, I enjoyed working at my parent’s 8 Re/MAX offices in New England. Now, I relish having my own real estate brokerage where my family is able to pop into the office for a snack and mingle with our clients and staff members. Jim and I and our four kids LOVE the island lifestyle - the exotic wildlife, lush vegetation, natural beaches, warm weather and the small-town community atmosphere are unlike anywhere else in the country. 

To say Sanibel has a strong sense of community is an understatement. The island has truly become our home - a place where my children have grown up attending The Sanibel School (which, by the way, is a National Blue Ribbon School of Excellence), summer camps at the Sanibel Sea School, and after school activities at the Library, the Rec Center and Big Arts Herbert Strauss Theater. From the organized bird and beach walks at SCCF (Sanibel Captiva Conservation Foundation), to the loads of events held at the Community House, there is something for everyone to get involved in the island community. 

The community of Sanibel continues to amaze us with the constant outpour of love and support.

Thanks for taking the time to get to know me. It would be an honor to help you on your real estate journey. Please continue to browse our site and don’t hesitate to call or email me with any questions about this beautiful sanctuary island we are blessed to call home.
