In fact, many of our team members’ longevity can be measured in decades rather than years. Why? SEM is committed to fostering a positive, team environment that places high value on acumen, integrity, respect, and excellence at all levels, allowing our team members to build rewarding careers and develop professionally. As a result, SEM is the indisputable industry leader in intellectual capital, allowing us to provide deep industry expertise and continuity of service to our client base.
