Position Overview

We are seeking a highly organized and detail-oriented Assistant Manager to support the Practice Manager at our Union Square location.

This role is the backbone of our back-office operations — the ideal candidate is a proactive problem-solver who thrives on keeping things running smoothly behind the scenes. This individual takes ownership of inventory, reporting, staff scheduling, and administrative processes, freeing up the Practice Manager to focus on higher-level clinic strategy. The right candidate is trustworthy, discreet with sensitive information, and comfortable juggling multiple ongoing responsibilities without losing sight of the details.
