The Guilford office of William Pitt Sotheby’s International Realty recently made a $1,000 donation to The Sarah Foundation in Guilford, a family of agencies that provide programs and services for residents with intellectual disabilities.

The gift was part of a companywide charitable effort on the part of Pitt and its new partner, Building and Land Technology (BLT). After taking a private equity stake in the brokerage firm at the end of 2008, BLT gave $1,000 to each of Pitt’s 20 offices for discretionary giving.
