About Arenal Advantage

Phyllis Caroline Adee is an international real estate broker, franchise owner, and luxury development specialist leading Coldwell Banker’s presence in Costa Rica’s La Fortuna and Arenal region. With a collaborative, relationship-driven approach, she focuses on strategic listing leadership, eco-luxury communities, and helping clients discover exceptional properties that reflect both lifestyle and long-term value.

Before establishing her Coldwell Banker office in Costa Rica, Phyllis was a dedicated team member within one of Coldwell Banker’s top-performing development-focused mega teams in the United States. Working alongside experienced leadership and agents, she gained firsthand insight into the systems, structure, and teamwork behind large-scale subdivision and exclusive inventory sales. That experience shaped her understanding of how high-level real estate operations function behind the scenes, from developer collaboration and marketing strategy to scalable listing management, lessons she now applies thoughtfully as she helps grow the Arenal region within the Coldwell Banker network.

Phyllis brings more than three decades of entrepreneurial experience to her role, including international franchise development where she oversaw multi-unit expansion, construction, and operations across multiple markets. This background allows her to work comfortably with developers, investors, and buyers alike, offering guidance grounded in both business strategy and personal connection.

Today, she serves as the Exclusive Listing Broker for Arenal Hills Villas, a premier eco-luxury gated community featuring over 150 custom homesites inspired by the design standards of the renowned Springs Resort & Spa. Working closely with the development team and the Coldwell Banker Costa Rica network, Phyllis is helping introduce a structured, collaborative approach to luxury real estate in the region while supporting the long-term vision for La Fortuna’s growth.

As a Costa Rican citizen with extensive international experience, Phyllis blends local insight with a global perspective. Known for her integrity, humility, and team-oriented mindset, she believes real estate is built on trust, communication, and shared success, values that guide her work with clients, developers, and colleagues throughout the Coldwell Banker community.

Guided by collaboration, integrity, and a deep respect for Costa Rica’s natural beauty, Phyllis believes exceptional real estate is not just about property, it’s about creating meaningful connections, lasting value, and a place to truly belong.

 

On the personal side… I am in love with the biodiversity, the sunshine, the rain, and the vibrant energy of La Fortuna. I am on a journey toward becoming more self-sufficient and watching that dream slowly come to life. Life currently includes a seven month old German Shepherd who is deep in the adorable oversized puppy phase and keeping me very busy.

Recently fulfilled a long-term dream of purchasing land with the help of Nick Ruhlow. Can't express enough of what a wonderful experience the entire process was. Nick was a true professional from start to finish. Not to mention easy to be around. He is straight forward and honest. He was patient with viewing properties and helpful with all our questions. Trust was built quickly, and honestly, I am not sure I would have felt so solid without his help and guidance. He has referred me to other professionals needed and has definitely gone the extra mile. I encourage anyone who is selling/buying to meet with Nick.
