GEOFF MCCABE, CO-OWNER, CEO
Geoff was raised in Seattle, Washington, and graduated from The Evergreen State College, in Olympia, before getting a Master’s degree in Physics from the University of Central Florida. After that, he started his first business, Seventh Sense, designing and selling jewelry and gift products, which gradually grew into a $6 million per year enterprise, manufacturing in many countries in Asia, and selling worldwide. For three years during that time, he also owned and operated a chain of 30 retail stores, called “The Mountain” which were based in the New England area. He sold the company to his partner and moved to Costa Rica.
Geoff has been interested in real estate and the creation of communities since he was a child. His great grandfather built the famous Mexican surf town of San Miguel in Baja California, where Geoff spent a lot of time when he was growing up. His great, great grandfather, Robert McFadden, built a railroad and founded the town of Newport Beach, where McFadden Wharf and McFadden Avenue are still named for him today. Geoff was raised on stories about these men, and has their experiences in mind while living in Costa Rica and playing a part in the growth of the communities of Montezuma and Malpais.
Geoff has dedicated himself to the conservation of Costa Rica’s wildlife and improving the lives of its poorer citizens. He is immensely grateful to the people of Costa Rica for allowing him to move to the most beautiful country in the world and raise his daughter, Serafina, who was born here. He is a founder of Rainsong Wildlife Sanctuary in Cabuya, which is working on reforesting and protecting and reintroducing animal and bird species that have become extinct in our part of Costa Rica.
Geoff can be found searching the jungle for orchids, photographing birds, playing with snakes or scorpions, studying green building, attempting to surf, or practicing firedancing.
NOA SERGEV, INTERNATIONAL PROPERTY MATCHMAKER
More than two decades ago, Noa arrived in Costa Rica as a solo traveler making her way through Central America. She hadn’t planned to stay long, but the country’s natural beauty, vibrant culture, and welcoming community drew her in with surprising force. The decision that followed shaped the rest of her life—she made Costa Rica her home, raised her family here, and built a career rooted in the place she loves.
Before entering real estate, Noa spent over ten years deeply involved in property management and vacation rentals. Her work went far beyond handling bookings: she oversaw home maintenance, collaborated with service providers, and guided homeowners through the challenges of owning and renting property in a coastal, rural environment. This firsthand experience gives her a practical understanding of what buyers should consider when choosing a home or investment on the Southern Nicoya Peninsula.
Fluent in English, Spanish, and Hebrew, Noa moves easily between cultures, helping clients feel supported and informed as they transition into life in Costa Rica. Known for her outgoing personality and ability to connect with people from all walks of life, she has cultivated a wide circle of trusted local contacts. She often becomes a resource not just for finding the right property, but for understanding neighborhoods, navigating services, and settling into the community.
Noa is particularly drawn to clients seeking a lifestyle that values nature, simplicity, and authenticity. She enjoys working with families, newcomers, and anyone who wants to live with intention—whether that means building a home, generating sustainable rental income, or simply finding a peaceful place to belong.
Outside of her work, Noa spends her time exploring nearby beaches and trails, supporting community efforts, and enjoying life with her children and close friends. She continues to feel grateful for the chance encounter that brought her to Costa Rica all those years ago.

MERCEDES ELIZALDE, INTERNATIONAL PROPERTY MATCHMAKER
Mercedes first arrived in Costa Rica in 2001 to join a marine-mammal research and conservation project on the Caribbean coast. She had been volunteering with similar organizations in Argentina since 1991, and her move was meant to be temporary. But Costa Rica changed her plans. Its biodiversity, culture, and way of living resonated so deeply that she never left. Over two decades later, she still calls it home.
A graduate in Tourism, Mercedes built a professional path that merges travel, nature, and meaningful experiences. She founded her own thematic tour company bridging Costa Rica and Argentina, designing itineraries focused on culture, wellness, and connection with the environment. Her programs encouraged travelers to slow down, experience local life, and choose vacations that supported well-being.
Her career eventually expanded into hospitality and luxury vacation management, where she spent more than a decade advising property owners and guests with very different expectations—from adventurous backpackers to high-end clients seeking privacy, concierge-level service, and curated local experiences. Along the way, she became an expert in how properties function as both homes and investments, what travelers value, and what it takes to create long-lasting satisfaction in challenging coastal climates.
Today at Tropisphere Real Estate, Mercedes brings that same balance of practicality and purpose to her clients. She has a particular affinity for buyers seeking a lifestyle aligned with nature, well-being, and community—first-time expats, families choosing a slower life, and investors who appreciate long-term value and responsible development. Her approach is analytical, honest, and personalized: she focuses on clarity, informed decision-making, and matching each client with options that align with their goals, budget, and lifestyle, speaking fluent English and Spanish.
After nearly 25 years in Costa Rica, Mercedes remains driven by the idea that where you choose to live should support who you are becoming. She sees real estate as an extension of quality of life, not just an asset—and loves helping others find a place where they can thrive and truly feel at home.
