ABOUT ONYX

Your practice, fully supported.

High level administrative support and streamlined operations for mental health professionals

From Overwhelmed to Optimized

ONYX is known for the ability to take what feels like a “hot mess” and transform it into an organized, efficient, and thoughtfully managed operation. This transformation is not just about organization—it’s about creating a foundation that allows practice owners to lead with clarity and confidence.

ONYX serves as both a strategic partner and hands-on operator—bringing a rare combination of big-picture thinking and meticulous execution. We believe that when administrative systems are strong, everything else flows.

Your time is valuable.
Your work is meaningful.
Your practice should support both.

A More Intentional Approach to Support

ONYX is not a task-based service.
We operate as an extension of your practice.

Our work is rooted in understanding the full scope of your operations—from client communication and scheduling to billing workflows, EHR management, and internal processes. We don’t simply complete tasks; we design systems that support the long-term growth and sustainability of your practice.

Clients often come to ONYX feeling stretched thin—managing the demands of their business while trying to remain fully present for the clients they serve. We step in to create structure, restore balance, and ensure that the day-to-day operations of the practice run seamlessly behind the scenes.

At ONYX Admin Solutions, we believe that exceptional practices deserve exceptional support.

Her background spans multiple industries, equipping her with a refined ability to build systems, anticipate needs, and create order in even the most complex environments.
