    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.

    Moriah brings a depth of real estate experience as an agent with Harcourts Island Properties. Her experience comes from her title and escrow background as a sales executive with First Hawaii Title Corporation from 2016 to 2017.

Moriah graduated in the top 1% of her class and was inducted into the nation's oldest honor society, Phi Beta Kappa.

She is quite observant and is willing to do whatever it takes to make transactions as smooth and as stress free for her clients as possible.
