Randall Taussig

Founder/Expert EOS Implementer/Coach

Randy helps his clients gain clarity and build confidence to be their best.

His career is defined by his passion for helping entrepreneurs run impactful organizations. He’s an experienced entrepreneur who understands the challenges of building a GREAT company.

Let’s talk history.

Randy’s entrepreneurial journey dates back to 1860. No, he’s not 150+ years old, but he does have family roots that helped him become who he is today.

His great-great-grandfather started two small bakeries in Washington, D.C. in 1860 that grew into a $150 million molasses and sugar refining business called Sucrest Corporation. They invented products that are still on the market today. Ever heard of Grandma’s Molasses™?

He joined the family business fresh out of college from the University of Delaware, working in finance, marketing, then sales and operations. He helped grow the business both organically and through acquisition, which led to its sale to a larger food conglomerate.

Then he pushed further:

  • Managed the marketing and sales for a $40M pharmaceutical packaging business
  • Lead the marketing and operations for a national trade association
  • Built two consulting practices
  • Earned his Private Pilot’s license, instrument rating and accumulated over 1,500 flight hours
  • Founded BlueCore Leadership

He now runs BlueCore Leadership where he helps other entrepreneurs navigate the path to success by simplifying their business practices, building confidence, and breaking through barriers.

Tiffany Harker

Client Experience

Tiffany joined BlueCore Leadership in 2016 and brought with her a “Grow or Die” mentality. She has grown within her role and now oversees the business’s day-to-day operations, keeping things running smoothly within BlueCore. She also offers customer support to our clients, ensuring they have an exceptional experience.

Having lived as a minor league baseball wife for 7 years, she learned to adapt quickly and connect easily with people. Her background as the Conference Coordinator at the College of Charleston and the Director of Training at LearningRx made her the detail-oriented person she is and the right one to make sure everyone and everything runs efficiently.

Tiffany holds a bachelor’s degree from the College of Charleston in Corporate Communication. She not only keeps BlueCore organized but also manages the busy schedules of her 2 children and collegiate baseball coach husband. When she’s not working (and sometimes even when she is) you can usually find her at the baseball field!
