Encouraged by the positive response from our client over the ensuing years, Simpson & Simpson Management Consulting was created as a separate entity to further expand the firm’s services into program and construction management. Today, S&S is a full-service professional management organization serving a variety of clients and markets in the Southern California area.

“Delivering peace of mind through performance-driven achievement”

Our clients know what this means….it is the peace of mind they experience in knowing that we understand their needs, challenges and concerns and know what it takes to get the job done. Every S&S employee is empowered and challenged to continually improve. To accomplish this, S&S invests heavily in the training of each employee so they remain at the forefront of their respective disciplines. S&S employees are pragmatic in analyzing problems, proactive in finding solutions and persistent in their desire to achieve successful results.

Our philosophy of performance-driven achievement applies to corporate citizenship as well. As a small business with strong ties to local communities, S&S is proud of its active involvement with organizations such as Habitat for Humanity, Boy Scouts of America and our participation in community-based internship programs. S&S employees apply the same drive and commitment they have for their client’s projects to their community activities.
