About Alex Santos

Founder, Nimble Advisors | Fractional CHRO and HR Consultant Serving Miami and the United States

Alex Santos is the founder of Nimble Advisors, a fractional HR consulting firm based in Miami, Florida, serving small and mid-sized businesses across the United States. For more than 20 years, Alex has helped business owners turn human resources from a reactive function into a strategic advantage — building the systems, structures, and leadership infrastructure that let companies scale without breaking.

Alex works most often with founders and CEOs running 10 to 250-person organizations who have outgrown ad-hoc HR but aren't ready for a full-time CHRO. His clients span hospitality, professional services, accounting, legal, logistics, healthcare, and education — industries where people decisions directly drive revenue, compliance exposure, and client outcomes.

A Strategic Approach to Human Resources

Most HR consultants start with policy. Alex starts with the business.

Every engagement at Nimble Advisors begins with the same question: what is this company actually trying to accomplish, and where are people systems either accelerating or blocking that outcome? That framing comes from Alex's background in instructional systems design and organizational development — disciplines that treat performance as the product of clear goals, aligned systems, and measurable feedback loops, rather than as a function of individual effort alone.

The result is an HR practice that looks different from traditional consulting. Handbooks, SOPs, and compliance documentation are built to support specific business outcomes, not to check boxes. Performance systems are designed to catch issues early, before they require formal intervention. Leadership development is tied to line-of-sight business goals rather than abstract competencies.

Credentials and Background

Alex holds an M.B.A. from the University of Miami and an M.S. in Instructional Systems from Florida State University — a combination that bridges business strategy and the science of human performance. He previously held the Senior Professional in Human Resources (SPHR) certification from HRCI, reflecting more than two decades of senior-level HR experience across private industry.

His areas of focus include:

Strategic HR planning and organizational design. Fractional CHRO leadership for growing companies. Employee handbook and SOP development. Compliance, including I-9, wage and hour, and state-specific employment law. Performance management systems and coaching infrastructure. Leadership development and manager training. Talent acquisition strategy and structured hiring processes. Compensation strategy and employee benefits design.

In addition to his consulting work, Alex co-founded Miami Payroll Center in 2004, a payroll services firm serving small to mid-size employers. That operational background — running a service business, managing compliance across hundreds of client organizations, working directly with founders on the financial mechanics of employment — informs how he approaches HR strategy today. He understands what it actually costs to get people decisions wrong, because he has seen it from both sides of the employer relationship.

Industries Served

Alex and the Nimble Advisors team work with clients across several sectors where HR infrastructure is particularly consequential:

Startups and high-growth tech teams navigating rapid headcount growth and equity-heavy compensation.

Professional service firms — accounting, legal, consulting — where people are the product and retention directly drives revenue.

Healthcare and medical practices facing physician and clinical staff complexity, credentialing requirements, and heightened compliance exposure.

Non-profit organizations balancing mission-driven culture with the operational discipline funders and boards expect.

Hospitality and service-based businesses managing high-turnover workforces, wage-and-hour complexity, and multi-location operations.

How Nimble Advisors Works With Clients

Nimble Advisors offers four primary engagement models: fractional CHRO leadership for companies that need executive-level HR strategy on a part-time basis, HR consulting for project-based work such as handbook development, compliance audits, and SOP creation, performance coaching for managers and leaders working through specific team or individual challenges, and employee benefits strategy and broker coordination.

Alex personally leads engagements. Clients work with him directly, not through account managers or handoffs. That model is intentional — it keeps the work close to the business context it needs to solve for, and it's why Nimble Advisors has stayed deliberately focused rather than scaling into a staffing model.

Writing and Thought Leadership

Alex writes regularly at HR Briefs, Nimble Advisors' publication on strategic human resources for small and mid-sized businesses. Topics range from manager development and performance management to compliance updates, hiring strategy, and the evolving role of HR in growing organizations. His writing is aimed at founders, CEOs, and operations leaders who need frameworks they can actually apply, not generic HR commentary.

He also participates in the Gentlemen's Journal mastermind community and speaks occasionally on topics including organizational development, performance improvement, and the economics of turnover in small businesses.

Based in Miami, Working Nationwide

Nimble Advisors is headquartered in Miami, Florida, and works with clients across the United States. Alex has deep familiarity with Florida-specific employment law — including the Florida Choice Act, state wage-and-hour provisions, and the regulatory environment for Florida healthcare and hospitality employers — while serving companies in dozens of states through Nimble's nationwide practice.
