Gail was born and raised in western Massachusetts, about as far away as one can possibly be from Hawai’i and still be in the United States. Gail arrived on O’ahu for a one-month vacation in 1980…and stayed to make Hawai’i Nei (beloved Hawai’i) her new home state. Gail has been loving and exploring the islands, people, and culture of Hawai’i for the past 40 years. She bought her first property on O’ahu in 1983 and, during the 45-day escrow period, earned her State of Hawai’i real estate license. Just two years later, she purchased the company she’d been working for; upon selling that business in 1986, she founded and built Fidelity Properties from the ground up.

Over the past 30+ years, as owner and principal broker of Fidelity Properties, Gail has developed a market savvy which has enabled her to survive and thrive through the highs and lows of fluctuating real estate trends. She’s learned that there is opportunity in every situation, but that in order to maximize every opportunity, solid strategies must be in developed and utilized. Throughout changing and challenging real estate cycles, Gail has assisted buyers, sellers, and investors to benefit in every type of market, and she can assist you, too.

Fidelity Properties is located on the Windward side of Oahu and Gail has an in depth understanding of the diverse market that makes each house unique when it is up for sale. We started working with Gail to prepare our property for sale, realistically set the price for listing, and stage the property to attract the right buyers. From listing to successfully closing at asking price in 60 days during a slow market is a testament to Gail and Fidelity Properties to help us make the most from our property and close the deal. Gail is absolutely fantastic and we couldn't be happier.
