Nancy Calabrese, Founder & CEO

Nancy is passionate about a properly executed pre-sales process – engaging with prospects, uncovering their needs, and turning them into qualified leads. Her unique approach, positive attitude, and relentless attention to detail are derived from her recruiting experience.

Upon graduation from Penn State University, Nancy began her career in New York City as a recruiter for a national retailer and Fortune 500 company. After honing her skills for eight years, Nancy made the natural transition to the search industry, recruiting and placing insurance professionals.

In 1991 she founded Professionals Unlimited Inc, specializing in insurance industry recruiting. She saw the need for better quality, highly specialized, qualified lead generation and, in 2011, created One of a Kind Solutions, which was rebranded One of a Kind Sales in 2018. Nancy employs a unique approach to solving problems using consultative selling.
