Biedri?š is well-known for his involvement in several charities. He was active in Warriors community programs during his rookie season, participated in the team's Thanksgiving Food Serving at Patrick David's Cafe in Danville, hosted a halftime Holiday Party for underprivileged children at the Warriors game vs. Memphis on 12/22, attended the Warriors Kids Day celebration, as well as the Run With TMC Fantasy Camp reception, and also visited injured American troops just back from Iraq at the National Naval Medical Center outside of Washington, D.C. when the team was in the area in early March. This level of activity is impressive, as his English language skills were poor when he came to the U.S.; he also taught himself to speak English in six months while training in Los Angeles prior to the 2004 NBA Draft.
