During his time there, Tzvi was able to help over 4,500 clients and their families, helping guide them through the most difficult of times. During his professional career in recovery, Tzvi also began a non-profit, The YY House. Its mission was to create a dynamic recovery community for those in sobriety. The YY House brought over 500 people together to join in different events that united the community.
