Meet the Team


SLI’s instructors hold the most respected certifications in the networking industry. To enable our instructors to be true experts in their field, we have developed an instructor specialization program. Each instructor is assigned as the resident expert for a specific technology area and is responsible for enhancing the existing curriculum to best fit the needs of our customers. By having such focus, our instructors excel in training delivery and development.
