Jamie Kastelic is Southwestern Michigan Realtor known for strategic marketing, strong negotiation, and an unwavering commitment to the people she represents. Based in St. Joseph and serving communities throughout Southwest Michigan, Jamie has built her business on relationships, results, and a highly personal approach to real estate.

With a degree in sociology/psychology from Lake Superior State University, Jamie brings a deep understanding of people and human behavior to every transaction. She knows how to listen, read a situation, navigate difficult conversations, and remain calm when the stakes are high. Most importantly, she knows how to advocate. Whether negotiating a purchase, positioning a property for market, or solving a problem behind the scenes, Jamie approaches her clients' goals as if they were her own.

Marketing is another hallmark of Jamie's business. She believes a home should never simply be placed on the market—it should be positioned to stand out. Her approach combines compelling property storytelling, sophisticated digital and social media marketing, targeted advertising, and the global reach of @properties Christie's International Real Estate. She is constantly looking for new and creative ways to reach buyers both locally and in important feeder markets, particularly Chicago and the surrounding suburbs.

That perspective is especially valuable in Southwest Michigan, where real estate is so closely connected to lifestyle. From St. Joseph and Stevensville to the communities stretching along the Lake Michigan shoreline, Jamie understands what draws people here: the beaches, charming downtowns, waterfront living, sense of community, and the opportunity to feel a world away while remaining remarkably close to Chicago. She helps clients understand not only the homes, but the subtle differences between the communities and lifestyles surrounding them.

Jamie's professional and community accomplishments have earned recognition including 40 Under 40 and being named one of Southwest Michigan's inaugural BOLD Women of Business. But some of the experiences that have most shaped her approach to life and business happened far outside real estate.

After facing breast cancer at a young age, Jamie became an outspoken advocate for women navigating breast cancer, mastectomy, body image, and survivorship. Her advocacy ultimately took her to New York Fashion Week, where she walked the runway for AnaOno, helping challenge traditional perceptions of beauty and representing women living confidently after mastectomy. Her story and advocacy have been featured twice in Forbes, bringing a national audience to conversations surrounding vulnerability, empowerment, and women's choices after breast cancer.

Those experiences reflect a quality that has followed Jamie throughout every chapter of her life: she believes deeply in showing up for people and isn't afraid to use her voice when it matters.

Today, she brings that same determination to her clients. Whether she's marketing a luxury or waterfront property, helping a Chicago buyer discover Southwest Michigan, representing an investor, guiding a first-time buyer, or helping a longtime homeowner sell a place filled with memories, Jamie understands that real estate is rarely just about the house. It's about the people, the transition, and what comes next.

Away from real estate, Jamie is happiest with her husband, Brian, and their two sons, Ethan and Brady. She loves the Lake Michigan shoreline, spending time at the beach, hiking, animals, and the Southwest Michigan lifestyle she has the privilege of introducing to so many of her clients.

Backed by @properties Christie's International Real Estate, Jamie combines local knowledge, global exposure, creative marketing, and relentless advocacy to deliver an experience that is distinctly her own.

For Jamie, the goal isn't simply to close a transaction. It's to make sure her clients know they had the right person in their corner.
