Never stop learning. That philosophy has served Dr. Jay Cohen well throughout his entire career, as founder of Signature and as a doctor beforehand. He encourages asking the hard questions and digging deep to find answers. Continuous improvement isn’t just a buzzword concept at Signature; it is built into the culture.
Dr. Jay started Signature Consultants in 1997. With a medical degree from Cornell University, he practiced internal medicine and gastroenterology in South Florida for 20 years before finding himself increasingly drawn to the business side of the practice. He wanted to create a brand new enterprise, one that — like medicine — combined both science and compassion. IT staffing sang out to him because it not only worked to solve current technological problems, but it helped enrich people’s lives, too. To drive Signature forward, Dr. Jay steers the company's strategic vision and stays hands-on with scaling the culture to keep up with national growth. In fact, Signature recently joined forces with DISYS and became one of the top staffing providers in the world.
Beyond the office, you can find Dr. Jay spending time with his family, reading historical novels (as well as espionage and thriller novels by authors like John le Carré and Lee Child), and competing in Texas Hold ‘Em Poker Tournaments. In fact, he plays in the World Series of Poker every year.
Chief Administrative OfficerView profile
One part visionary, one part lawyer, Mark manages to stay a step ahead — in business, strategy, IT staffing, you name it — while remaining utterly present when you talk to him.
As Chief Administrative Officer at Signature Consultants, Mark heralds the importance of getting to know and understand people. He leads by example. Growth mindset isn’t a buzzword for him. It’s a way of life. And he makes sure the people throughout the organization have the feedback and tools they need to learn, grow and thrive.
Mark joined Signature in 2000, following undergrad and law degrees from the University of Michigan, being senior partner at the leading law firm of Honigman Miller Schwartz and Cohn, and serving as EVP at premiere medical real estate development firm Rendina Companies.
He’s a passionate Bob Dylan and Bruce Springsteen fan (and a music lover, in general) who isn’t afraid to call on a favorite lyric to drive home his point. Mark calls Fort Lauderdale home, but makes his way across the U.S. for speaking engagements about the future of work and technology. You’ll want to meet him at your next conference.

Geoff has played a major part in helping organically grow Signature Consultants into one of the largest privately held IT staffing firms in the United States. Geoff’s values mirror that of Signature’s: integrity, hard work and treating people right. Geoff says these values were handed down from his mentors – his parents and grandfather. After joining Signature and working closely with Dr. Jay Cohen, the philosophy of “always do the right thing” has also become an important ideal that guides Geoff’s decisions.

Whether focusing on business development, sales, operations, our enterprise accounts, clients or consultants, Geoff is known for his unwillingness to compromise on quality, never giving up and for always striving to “do the right thing.”

His motto: “learn from your mistakes, always have fun and enjoy the ride.” He believes relationships are built over time through mutual respect, open and honest communication, trust and the ability to relate to and accept diverse points of view.
In his “downtime,” this 30-year staffing industry veteran can be found on the golf course, volunteering in support of the Charlotte Region, or spending time with family and friends. Geoff is a graduate of East Carolina University and UNC-Charlotte where he studied Political Science.

Brad began as a Recruiter and worked in many roles across the enterprise, all the while holding his vision of embedding professional and personal development within Signature’s culture. When Brad joined the Training and Development team in 2011, it was the beginning of something big. Signature quickly became known among international organizations and talent innovators from all industries. The Association for Talent Development (ADT) has since recognized the company among the Top 125 Training Organizations in the U.S. many times over.
Signature’s culture is a source of company pride. It’s renowned for being highly collaborative, cohesive, and supportive of individual growth. Brad’s unmatched energy, innovative mindset and insight to all aspects of the business are a big part of the reason why Signature thrives.
Many see Brad’s passion and integrity as rocket fuel for company growth, as well as daily sustenance for Signature’s team members. Meanwhile, he sees the flip side, “It’s the superstars around me that make me better every day.”
At the end of the workday, the University of Florida grad burns any residual energy by working out or joining friends for golf, staying involved with charitable work and spending time with his wife Brooke, sons Reese and Cooper, and Goldendoodle Murphey.

As a teacher, lawyer, former U.S. government compliance office, and HR professional, Candace Whitaker is an advocate for growth and development. After becoming Signature’s eighth employee in 2004, she put her insatiable intellectual curiosity and problem-solving acumen to work, and built the company’s HR department from the ground up.
Signature’s friends-first approach meshed well with her gift of embracing the individual and connecting them to something bigger. Growing up, Candace’s family sought out foreign countries and cultures, and she attributes her exposure to and appreciation of cultural diversity with providing her resources for problem-solving and developing forward-looking programs and policies. Her mantra: “Keep evolving your thinking.”
Candace has been instrumental in how employee talent blossoms into shared strength on a team, and in making meaningful relationships part of the Signature way. “I thrive by understanding what makes individuals unique and exploring topics outside my box,” she says.
Candace’s passion for witnessing the expression of talent doesn’t end with her job duties. This Wayne State Law School and Michigan State University graduate is a fan of art, theatre, comedy, dance, and poetry. She dabbles in various arts and crafts, and on occasion, her creativity bubbles up as doodles in the margins of her meeting notes.

Lydia started her career as a recruiter and shortly thereafter transitioned into sales and then management. Passionate about the world of work, she has spent the last two decades in employment.
Working in staffing, permanent search, Recruitment Process Outsourcing (RPO), Managed Service Provider (MSP) and Vendor Management System (VMS), she has helped Fortune 1000 companies drive their contingent workforce strategy both nationally and globally.
One of SIA’s “Top 100 Women in Staffing,” she works in and outside the industry to make the world of work more inclusive for all.

The promise to Do No Harm, Do the Right Thing and interact with everyone you encounter as a friend first directly aligns with her focus and personal values.
If you haven’t met Lydia she believes in a good belly laugh a day. She is a bit of a thrill seeker and has been skydiving and flown an airplane in a “Top Gun” dog flight. On the slower side, Lydia likes photography, walking, the beach and spending time with her family.

When Philip Monti stepped into his role at Signature, he had already built a broad base of experience in accounting and finance. With a Bachelor of Science in Accounting from University of Florida and a Master of Science in Accounting from the University of North Florida, his career began at Arthur Andersen as an Audit Senior, then moved to MPS Group/Adecco and Acosta. His responsibilities spanned accounting, financial forecasting and reporting, M&A, SEC Compliance, FP&A, risk management and tax and treasury.
Philip’s expertise lies in reading the story told by the numbers, understanding the relationship between them, and providing actionable information. And while his analytical mind fuels his ability to identify and articulate, he balances this with a focus on emotional awareness, especially in situations that challenge teams or require organizations and customers to adapt.
When Philip isn’t working to prepare the organization for success in any economic environment, you can find him rooting for his favorite football team (Go Gators!), running, reading, and spending as much time as he can with his family.
