Brett Stewart leads business development at Ascend Recovery Center, building the strategic partnerships and referral relationships that connect clients to care. He works closely with hospital systems, primary care practices, employee assistance programs, community mental health centers, and other behavioral health providers to establish clear referral pathways into Ascend's programs. His work spans partnership development, education of Ascend's evidence-based programming for referring clinicians, coordination of referral protocols, and the long-term relationships that expand access to care across New Mexico.

The team at Ascend Recovery Center is a coordinated group of medical, clinical, nursing, and case management professionals. Recovery is a team effort, and each role has a clear part to play in keeping clients safe and moving treatment forward.

Because we offer the full continuum of care in one building, the same coordinated team supports clients as they step from detox through residential care and into outpatient treatment. Clients are not handed off to strangers as their needs change. This page describes the roles behind client care; where named clinicians and credentials are confirmed, they are added here.

What roles make up the care team?

Care at Ascend is shared across defined roles, each responsible for a different part of a client's treatment. Here is how those responsibilities are divided across the team.

Medical director

The medical director oversees the medical side of treatment, including detox protocols and medication decisions. Detox patients are seen by a provider within hours of arrival, and complex cases are escalated to medical leadership.

Clinical director

The clinical director leads the therapy program and clinical decision-making. Pre-assessment red flags are escalated to clinical leadership, and treatment plans are reviewed to keep care individualized and appropriate.

24/7 LPN nursing team

Licensed practical nurses are on site around the clock for detox and residential clients. They complete nursing assessments, monitor withdrawal using the CIWA and COWS scales, and keep the medical team informed as clients stabilize.

EMDR-trained therapists

Our therapists deliver evidence-based care including CBT, DBT, and narrative therapy, and we have EMDR-trained therapists on staff for trauma-informed work. Family therapy is available with the proper releases.

Case managers

Case managers connect clients to practical support, including FMLA and job coordination, legal and court support with proper releases, and help with insurance applications and benefits such as SNAP. They coordinate step-down care and work with community housing partners as needed.

How does the team work together?

The team works together as a coordinated unit, not as separate silos. A single admission moves through nursing, medical, clinical, and case management hands in a coordinated way, so nothing about a client's care depends on one person alone. When a client's level of care changes, the team adjusts the plan together.

This coordination is possible because every level of care sits in one building. As clients step down from detox to residential to outpatient treatment, the same team carries their history forward, which keeps care consistent and reduces the gaps that can appear when a person is transferred between facilities.

Who coordinates a client's care as they step down?

As clients step down through the levels of care, their case manager and clinical team coordinate the transition together. Step-down coordination is the process of moving a client from a more intensive level of care to a less intensive one while carrying their history and treatment goals forward, and at Ascend it happens within one building rather than across separate facilities.

Case managers connect the practical dots that keep recovery from unraveling. They coordinate FMLA and job matters, provide legal and court support with the proper releases, help eligible clients apply for insurance and public benefits such as SNAP, and work with community housing partners when a client needs coordinated housing support. Family therapy is available with the proper releases, so loved ones can be part of the plan when it helps. Throughout, clinical leadership reviews treatment decisions to keep care individualized and accountable.
