    Anthony and Moriah Johnson


    Real Estate is often considered the largest investment someone can make and my goal is to make that process simple and easy to understand. With a background in lending and finance I'm one of those weird guys that enjoys the numbers. Having a passion for truly helping people and making my community a better place, I am committed to making the American Dream a reality for families in Hawaii. My past has many facets, but one of my proudest accomplishments is overcoming Cancer because it taught me at a young age that life is finite. Understanding this has been instrumental in my career because I focus on making things as efficient as possible to give myself more of that one thing we can't get back: Time. Bringing efficiency, dedication, and exceptional customer service to real estate my beautiful wife, Moriah Johnson, and I will make your largest investment an easy one.
