Gregory J. Lesak, Jr., special counsel at Jimerson Birr, focuses on having a deep understanding of the underlying business and specific needs of his clients.  He is results-driven and aggressive, but most importantly, being cost-effective is at the forefront of everything that Mr. Lesak does.  Over the years, he has developed a unique perspective for assisting clients, gained from significant experience as a transactional attorney, a litigation attorney, and as in-house counsel for a large publicly traded company.  As such, he has served as both the client and the attorney, which uniquely equips him to fully understand the business needs of clients and solve problems.  As a solutions-focused lawyer grounded by extensive business knowledge, when representing clients, Mr. Lesak focuses on problem solving and sees this as the core role counsel should play.

Prior to joining Jimerson Birr, Mr. Lesak was in-house counsel for a large publicly traded company after working as an attorney for several prominent law firms specializing in complex commercial litigation and real estate development.  Over the years, he has developed a diverse skill set by working on a wide range of matters.  Specifically, Mr. Lesak started his legal career with a local law firm doing large real estate transactional and land use work before transitioning to complex commercial litigation.  From there, he would transition to serve as in-house counsel leading multiple attorneys and litigation matters, and also creating and managing a large contracting program for the company. Managing litigation over the years has allowed him to develop a strong understanding of risk versus reward as well as case value, which he utilizes in every matter he works on to this day.

Mr. Lesak has particular expertise in landlord tenant leasing and dispute resolution, construction contracting and dispute resolution, complex commercial litigation, insurance disputes, and client contract drafting and negotiations. Additionally, he has extensive expertise in contract automation and cyber security.

Mr. Lesak grew up in Orange Park, Florida from the age of 5 and has lived in the Jacksonville area most of his life. He currently resides in Julington Creek with his wife and two children.  In his free time, you may find him out on a boat tubing with his family, or at an area baseball field or basketball court coaching or cheering on his kids.  When he gets the chance, he loves to fish, camp, go to the beach, and spend his time outdoors.
