About Citronia Recovery

Founded through recovery and family experience.

Zack Zulkiewicz and his stepfather, Bill S., founded Citronia. Zack brought his recovery experience; Bill brought his experience supporting a family member.

The story

One family’s experience led to Citronia.

Zack moved from Connecticut to Los Angeles in 2015, became active in the local sober community, and worked at a rehabilitation center. His recovery experience led him to create a stable home for others in recovery.

Bill supported Zack and brought experience in operations and finance as a CPA. Together, they founded Citronia in 2017. Zack now serves as Founder and Owner, while Bill serves as Founder and Chief Financial Officer.

Today, staff explain house expectations, answer practical questions from residents and families, work with referral professionals and help residents connect with independent care.

Citronia’s role

Housing and clinical care have different roles.

Citronia provides sober living housing, not medical or clinical treatment.

Citronia provides

Substance-free housing, a shared-home environment, practical structure, and clear expectations for daily life.

Independent providers handle

Clinical assessments and services, treatment recommendations, admission decisions, insurance participation, and billing.

Since 2017, Citronia has built working relationships with independent treatment providers. With the person’s permission, staff can explore providers, arrange introductions and coordinate moves into or out of sober living.
