Leslie began her career in the greater New York metro area pioneering the way for others as New York State's first female certified Draftsman. Over two decades she advanced to project manager and executive liaison roles for the electrical/ mechanical departments, and eventually rose to the position of project coordinator, for many high-tech companies including; Revlon, PepsiCo, Union Carbide, Pitney Bowes, Pfizer Pharmaceuticals, ITT, and IBM Research Center. Among her many responsibilities, she was responsible for creating management level presentations working closely with R&D engineers, executives and other personnel and translating their input into tightly specified working sketches and supervising their final production by outside vendors.
Leslie went on to pursue graphic design at SUNY Purchase, NY and, over the subsequent 10 years, owned and operated an award-winning graphic design studio in consulting and direct marketing. 
Leslie wrapped up her private sector work as Studio Manager for an educational publisher, managed, scheduled, and coordinated a network of people for the production and publishing of math and science textbooks. She was also charged with maintaining the website, ensuring proper function, keeping information current, implementing and uploading changes periodically.
After relocating to Florida in 1999, Leslie shifted to serving in the non-profit sector. She devoted her first 10 years in Lee County as the Director of Volunteer Services/Meals on Wheels of Lee County, Inc. and Meals on Wheels Driver Coordinator/Community Cooperative Ministries, Inc. (CCMI). In that position she developed and implemented policy, products, and programs that grew the database to approximately 580 volunteers. In this position, she was responsible for managing and coordinating volunteers and their routes, delivering approximately 2275 meals per week to homebound customers. 

Beginning in 2012 she transitioned to the Dr Piper Center for Social Services in Fort Myers as the Director of the Faith in Action Senior Transportation Program.  At that same time, she rejuvenated the Faith in Action Program from the ground up, built new databases, and developed procedures and policies that brought the program back to life in Lee County.

Recently, Leslie retired from the Dr. Piper Center to focus on her family and her new position as the Secretary of the Lee County Republican Executive Committee.
