Dr. Cho studied business administration at Seoul National University. After gaining numerous experiences at various organizations, he received his masters degree. Despite reading thousands of management books, trials, errors, and regrets continued. At 4th year anniversary since founding a company, he studied management again. He realized that he couldn’t focus on the employees because he prioritized the profit of company. Based on this awakening, he created a unique management model called 'Happiness Management'. Happiness management aims to maximize the happiness of all stakeholders including customers, employees and shareholders, not profit.
