Board Officers
Josie has lived in Hilltop since 2008 and wanted to bring more diversity to the Hilltop Board. She is Latina and wants to represent her culture and bring different perspectives to the Board. During her free time, she likes to hang out at the sundial to see how many people she can get to say hello. If they don’t say hello, she gives them a card that says, “Today is ‘Say Hello to a Neighbor Day!’” She is currently serving on the Events Committee.
Graham moved to Hilltop with his husband in 2020. His hobbies include political and civic engagement which is one of the reasons he joined the board. He also wants to keep Hilltop a special place that draws in the community, so he joined the Membership Committee to welcome new members. When he is not selling homes as a realtor, you will find him skiing, walking his two dogs, or perhaps up in the air as he is also a general aviation pilot.
Sandi moved back to Hilltop in 2005 and joined the board as she strongly believes in the importance of neighborhood advocacy. In the past, she served as the President of a Civic Association in northern Virginia where they faced off with the county park system and school board to save 12 houses from a surprise demolition plan and find a reasonable alternative. She is currently a part of the Zoning and Nominations committees.
Lon is our current Treasurer of the board. He joined the board with a sincere interest in the 9th & Colorado Redevelopment Project, which united neighbors and empowered them for a common cause. Lon finds invigorating pleasure in gardening and cooking. In his free time, he enjoys traveling to Vietnam, which has captivated his interest, as witnessed by his frequent visits, with the current count at eight.
