As an Investment Services specialist, I focus on representing buyers and sellers of all commercial property types throughout the State of Hawaii.  Having operated as a commercial developer throughout most of my 15-year commercial real estate career in Northern California and Northern Nevada, I know the right questions to ask to identify my clients’ needs and match them to opportunities in the market.  Bringing a deep skillset of opportunity sourcing, underwriting, market analysis, acquisition, project oversight and disposition, provides me with unique insight to help my clients achieve their goals. My family and I moved to Hawaii in 2012 where I served as the Costar/Loopnet representative for the Hawaii and Alaska markets.  This experience provided me with a unique opportunity to meet and learn about all of the properties, owners, developers, brokers, lenders and other professionals involved in commercial real estate throughout these two great states.  Both markets are very unique and nuanced, and require creativity to tap into the market’s true potential, a skill I continue to hone on a daily basis.  It is rare that I won’t drive by a property and think, “how could the value of this property be maximized…and who do I know that could make it happen?”.  From there, it is about creatively bringing together the pieces of the puzzle.
