Dillas Quesadillas has promoted restaurant industry veteran Michael Mabry to chief operating officer, moving a seasoned operator into the seat that will oversee the brand's day-to-day restaurant operations as it manages growth.

The announcement, reported by the Bossier Press-Tribune, frames the move as an internal elevation rather than an outside hire — a signal that the fast-casual quesadilla concept wants operational continuity at the top. Chains in this segment typically hand the COO title to the executive accountable for unit-level execution: labor scheduling, food cost discipline, throughput and the consistency of the guest experience across every location.

What does this change for Dillas? In practice, a COO promotion concentrates operational authority in one leader, which matters most when a brand is adding doors faster than its bench of district managers can stretch. Mabry's background as a restaurant industry veteran suggests the company is prioritizing someone who has already run the P&L side of the business — where a single point of labor percentage or cost of goods can decide whether a new unit clears its break-even in year one.

Who is Michael Mabry?

The chain describes him as a restaurant industry veteran, a credential that in fast casual usually spans years across multi-unit management, training and store development. Operators promoted from within that track tend to arrive in the COO chair with existing relationships across the field organization, shortening the runway between the announcement and measurable changes in unit economics.

Dillas did not disclose in the announcement the specific figures operators watch most — unit count trajectory, average unit volumes or timeline for new openings. What the promotion does establish is leadership structure: Mabry now owns the operational agenda, while the brand's growth, franchise and real-estate decisions flow from the same C-suite.

Why the COO seat matters in fast casual

The quesadilla category sits inside fast casual, a segment where margins live and die on execution. Speed of service, ingredient prep and staffing levels drive both the top line and labor percentage. A veteran operator in the COO role is typically charged with standardizing those levers so each new restaurant opens with the cost discipline of the ones before it.

For a regional brand like Dillas, the promotion also reads as succession planning. Companies that elevate proven operators rather than recruiting externally often do so to protect culture during expansion — keeping the operational DNA that made early units profitable intact as the footprint widens.

The company has not announced additional executive changes alongside the move. How quickly Mabry's operational agenda translates into new units or revised unit economics will be the metric to watch in the quarters ahead.
