Lindsay Seslar
Leads admissions and communications. The voice on the other end of the admissions line and the lead on insurance verification, intake scheduling, and first-impression communication with families.

Lindsay Seslar leads the admissions team and the communications function at The Archangel Centers. Most people calling about treatment for themselves or a loved one will, directly or indirectly, be in conversation with Lindsay's team.
The first call is often the hardest part of treatment, both for the person calling and the family on the other side. The admissions team's job is to make that call as low-friction as possible without compromising the clinical care that follows.

What the admissions team owns
Lindsay's responsibilities span the admissions function and the broader communications function of the program:
- Admissions team leadership, the intake team that handles the 24/7 admissions line, conducts confidential clinical assessments, runs insurance verifications, and coordinates start-of-treatment logistics
- Communications, external communications, family-facing materials, and the broader voice of the program
- The single-call admission goal, building the team and the process that produces a clinical assessment, insurance verification, and a scheduled start date in the same call where possible
- Case management coordination, FMLA paperwork, short-term disability documentation, employment coordination, and (with releases) legal and court coordination
Why the first call is the work
By the time somebody calls an outpatient addiction program, they have usually been thinking about it for weeks, sometimes years. The moment they pick up the phone, the program either earns their trust or loses it. There is no second first call.
Lindsay's team is built around that reality. The admissions line is answered by humans, not a queue. The assessment happens in plain language. Insurance is verified in the same conversation when possible. A start date is offered the same day when clinically appropriate. Nothing about the experience is built to look slick on a website, it is built to feel manageable on the worst day of somebody's year.

The paperwork side of getting to treatment
Most people calling about treatment have practical concerns that have nothing to do with the clinical model. Will my employer find out? Can I take FMLA? What do I tell my probation officer? Lindsay's team handles all of it, FMLA paperwork, short-term disability documentation, employer-coordination letters, and (with signed releases) legal and court coordination.
That work is part of admissions, not separate from it. People do not just need a treatment plan; they need the conditions to actually show up for that treatment plan.
Call the 24/7 line, or verify online
