The Team

Harold Wingert


Sunflower Consulting Group, founded by Harold Wingert, specializes in all aspects of convenience store operations: consulting, store design, operational set up and ramp up, controls, inventory, and vendor contracts. Since 1985, when Mr. Wingert bought his first store, he has been engaged in the industry in some fashion, including operations, consulting, construction, and design. Over the last 33 years he has owned and operated 8 stores, successfully sold them, and has been consulting for the past decade. SCG has the team in place to provide the level of support you desire, from concept design, through opening the store, and establishing policy and procedures. SCG will work with vendors to achieve optimal sales and manage vendor contracts to take advantage of rebates or other incentives, which will result in more profits for ownership. SCG will assist ownership in hiring and training employees, continuing education, benefits package for management, and will assist in developing an employee manual. Sunflower Consulting Group looks forward to working with you to bring your concept to reality.
