Los Altos native Andy Sweet was a recent volunteer builder at a Habitat for Humanity seven-unit development in Dorchester, Mass. Sweet was part of a 20-member team sponsored by the James Sokolove law offices, where Sweet is Internet marketing manager.

“This has been a very fulfilling and rewarding experience,” Sweet said. “I feel honored to have played even a small role in helping some deserving families achieve their dreams of owning their own homes.”

Using volunteer labor and tax-deductible contributions of money, land and materials, Habitat builds and rehabilitates houses for low-income families. Habitat Boston, the affiliate in the Dorchester area, is financed by donations from individuals, community groups, corporations, charities, foundations, schools and religious organizations.
