Ascendant Leadership

Tzvi Heber CEO Ascendant NY detox center NY city


Tzvi Heber

Tzvi entered the field of recovery as a drug and alcohol counselor. The understood importance of treatment and feeling of purpose inspired his career change. With immense gratitude, he transitioned as the Director at Serenity Services. Tzvi then became the current CEO of Ascendant NY. Incorporating his professional and personal experiences, is a guiding force to provide treatment with humility, compassion, and dignity. As the leader, he works with his team to evolve the traditional culture of detox facilities. He seeks to fill the gaps where treatment falls short. Tzvi is cultivating individualized client-focused care- emphasizing that every person who walks through the door matters.

When Tzvi founded the YY House Foundation, these values were and remain most important. Every dinner held at his home is the anchor of the YY House, where individuals in recovery come together. He takes pride in the non-profit’s growth- now helping those struggling with access to resources, services, and more. Addiction is a disease defined by isolation. He continually works to create spaces that replace isolation with community. Whether at Ascendant NY, a YY House dinner, or at home with his beloved family- Tzvi remembers why he chose this path. He views his position as a gift and opportunity to provide someone support while seeking treatment. His passion has never wavered when saying, “There is help and recovery is possible.”
