“Brian,
This letter is being sent to formally thank you for your most gracious and much appreciated donation to Family Guidance Centers, Inc. (FGC). As you are aware, FGC is a not-for-profit organization which exists to provide prevention and treatment services for substance abusing individuals who may also suffer from an array of other related health problems. It’s been a real pleasure working with you Brian, as you are a true professional. You have come through on everything we have asked, and I would never consider another General Contractor on any project we undertake in the near future.”
