Tzvi then joined Serenity Recovery Center as the Director of Client Services. 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. Outside of his dedication to the community and his service to God, Tzvi spends time with his beautiful wife and three amazing children at his home in Teaneck NJ.
