With 3 years of management experience, I have learned many things about management, customer service and how to run a business. My skills are as follows: With my last job I raised sales by 30% in just the first 6 months of being promoted to Store Manager/General Manager. I was able to maintain that growth and expand on it over the course of 3 years. I graduated with my GED at the age of 15 and then shortly after I became a successful business owner.
