Dawn Greggo
Operations Manager 

Dawn moved to Honolulu 10 years ago and has been working with and helping local families since her arrival.


She studied English Literature with a minor in secondary education at the University of Texas, El Paso but instead of working as a school teacher found her way to working in many fast-paced growing companies helping them expand and succeed.

She learned that the business environment was exciting which lead her to work in 2008 as a mortgage loan processor and coordinator.

In her free time, Dawn loves to travel with her husband and entertain with their many friends from across the island.

Grateful for the opportunity to live in paradise, Dawn loves the work that she does and is excited to help others achieve their goal of owning a home in Hawaii.
