What We Do

Three Pillars of Operational Excellence

We've built our practice around the administrative functions that keep Florida businesses compliant, efficient, and positioned for growth.

Specialized Payroll Management

Construction and medical sector payroll isn't straightforward. Between certified payroll requirements, prevailing wage calculations, and the complexities of multi-state healthcare staffing, these industries demand specialized attention.

  • Weekly and bi-weekly cycle administration
  • Certified payroll documentation
  • Per diem and job costing integration

Executive Administrative Consulting

Growing companies often outpace their back-office infrastructure. We step in to provide the fiscal oversight and administrative rigor that scaling operations require—without the overhead of a full-time executive hire.

  • Financial controls and process design
  • Software and platform migration
  • Vendor and contractor management

Compliance & Risk Mitigation

Florida's regulatory environment has its own character. From SUTA rate management to proper worker classification, we maintain the documentation and processes that keep your firm audit-ready year-round.

  • Florida SUTA and federal tax adherence
  • 1099 and W-2 accuracy assurance
  • Worker classification review

Our History

Built on South Florida's Business Foundations

M923, Inc. was incorporated in Florida in 2019 with a clear purpose: to provide the kind of hands-on administrative partnership that growing businesses in Palm Beach County actually need.

We started working with a handful of construction firms navigating the complexities of certified payroll and prevailing wage requirements. Word spread. Medical practices dealing with staffing agency relationships and 1099 complications started reaching out. Today, our client base spans the industries that drive South Florida's economy.

Our approach hasn't changed since day one: know the regulations better than anyone in the room, communicate clearly, and treat every client's business like our reputation depends on it—because it does.

Meet the Managing Director

JM

Juan Maya Villamizar, MD

Managing Director

Board-Certified Rheumatologist | Palm Beach County

Juan's path to founding M923 wasn't typical for a corporate advisory firm—it started in a medical clinic. As a board-certified rheumatologist practicing in Palm Beach County, he spent years building a specialty practice while wrestling with the operational headaches that come with running a healthcare business in Florida.

Payroll complications. 1099 versus W-2 classification for locum tenens staff. SUTA rate management. The administrative burden of credentialing, billing cycles, and compliance documentation. He lived it all firsthand. And he watched colleagues at other practices—smart physicians who should have been focused on patient care—drowning in the same operational quicksand.

M923 was born from that frustration. Juan took the systems and processes he'd developed for his own practice and began offering them to other medical groups. Word traveled through the South Florida healthcare community. Then construction firms dealing with similar payroll complexity—certified payroll, prevailing wages, multi-job costing—started calling.

Today, Juan maintains his rheumatology practice while serving as Managing Director of M923. It's an unusual combination, but it works: he understands the operational pressures his clients face because he still faces them himself. There's no theoretical advice here—just practical systems built by someone who runs a business and pays employees every two weeks, just like you do.

When you work with M923, you're working directly with Juan. No junior associates, no account managers—just experienced, principal-level attention from someone who understands what's actually at stake.
