Building Something Different in Staffing
Principle Personnel Group (PPG) is a relationship-driven staffing organization built to deliver exceptional service to both job seekers and employers. Unlike traditional staffing firms, we combine the personal touch of owner-led support with the reach and systems of a multi-state staffing provider—ensuring that every placement, partnership, and interaction is guided by integrity, accountability, and results.
Our Founding and Mission
Founded in 2016 in the heart of Florida’s Treasure Coast, Principle Personnel Group began as a small staffing firm focused on Allied Medical and Dental placements. Over time, we grew into a collaborative network of experienced professionals and entrepreneurs united by a shared vision: to connect the right people with the right opportunities while building meaningful, long-term relationships.
Our mission is simple: to help job seekers find stable, fulfilling employment and to help employers build resilient teams that drive their business forward. That mission remains the heart of everything we do, from our placement process to our ongoing support after a placement is made.
What Makes Principle Personnel Group Unique
At PPG, we go beyond filling job orders. We build partnerships rooted in trust, communication, and personalized service. Each of our locations is led by owner-operators—local entrepreneurs who combine deep community knowledge with staffing expertise. This owner-led structure ensures responsiveness, accountability, and a vested interest in your success.
We believe that success is not a single event but a series of strong relationships. Whether working with a job seeker to find the right opportunity or partnering with an employer to staff key roles, our focus is on the long game: consistent support, transparent communication, and outcomes that matter.
Our Growth and Reach
What began as a specialized staffing firm has expanded into a multi-state operation with a national reach. Today, we successfully staff across multiple sectors, including industrial, administrative, healthcare, dental support, and professional roles. Our growth is driven by the success of the people we serve—both inside and outside the company.
From job seekers securing stable work to employers building strong teams, PPG’s services support a diverse range of staffing needs while prioritizing quality, fit, and long-term success.
Meet Our Team
Our team is made up of passionate, skilled professionals who bring fresh ideas, industry insight, and personalized service to every client and candidate interaction. We value innovation, collaboration, and a commitment to excellence that shows up in every placement and partnership.
You’ll always work with someone who listens, follows through, and takes ownership of your goals—whether you’re looking to hire top talent or find your next great opportunity.
David Stemm
President & Chief Executive Officer
David Stemm's journey into the staffing industry began unexpectedly in 1996, when he joined a small regional firm to lead their Risk Management department. However, his natural leadership and business insight quickly propelled him into Operations Management. In that role, David helped grow the company from just four locations to more than 60 throughout the Midwest and Northeast United States.
In 2016, David took a bold leap and founded Principle Personnel Group in Stuart, Florida, with the support of his wife, Hiba. His initial focus was on Allied Medical, Allied Dental, and Administrative staffing, helping professionals find meaningful work while meeting the needs of healthcare providers and businesses.
Three years later, an opportunity arose to help a colleague launch her own staffing business. From that moment on, PPG evolved into a collaborative platform where entrepreneurs could build their own staffing firms under one united brand.
David’s greatest passion is mentorship—giving others the tools and guidance they need to succeed as business owners. His leadership style is grounded in transparency, empowerment, and the belief that when we help others grow, we all grow together.
When he's not in the office, you’ll likely find David fishing, playing golf, or enjoying time with his family.
Gina Gonzalez
Owner, NE San Antonio
With over 20 years of staffing experience in the San Antonio area, Gina Gonzalez brings a level of expertise and tenacity that’s hard to match. She owns and operates PPG’s NE San Antonio location while also managing key corporate operations and national accounts for the entire company.
Gina specializes in light industrial staffing, placing both temporary and temp-to-hire workers in warehouses, distribution centers, millwork facilities, and rail yard operations. Her reach extends far beyond her local market—she also staffs skilled welders, general laborers, and warehouse personnel at distribution hubs across the country.
What truly sets Gina apart is her dedication to client success. She understands the pressures businesses face when it comes to labor and production. That’s why she prides herself on being responsive, reliable, and relentless in her pursuit of the perfect hire. Her client relationships often span 15+ years, a testament to her unwavering service.
Gina is known for saying, "I can’t guarantee a worker will show up—but I can guarantee the customer service you’ll get from me." This honest and straightforward approach is one of the many reasons clients trust her with their workforce needs.
She started her own business because she was tired of losing clients over decisions she couldn’t control. Now, as an owner, she ensures every client is treated with respect, responsiveness, and accountability.
In her downtime, Gina enjoys staying active, working out, and spending quality time with her kids at football and soccer practice.
