San Gabriel Valley Development


I have had the privilege of working with Matthew Krappman in the construction of West Ranch High School, a 52 acre, eighty million dollar project.  His dedication and attention to detail is truly remarkable.  Matthew is excellent at developing relationships with owners, contractors, and craftsman.  When differences of opinion came up, he was excellent at mediating the parties and moving the project along to keep the work on schedule...He is dedicated to excellence in all phases of construction...I have found him to be extremely intelligent, a wonderful communicator, and a person who leads with integrity, passion, and vision...He has earned my highest recommendation.

-Robert Vincent (Principal, West Ranch High School)

Matthew is intellectually gifted, morally and spiritually strong, has an excellent work ethic and will contribute to the success of any enterprise disproportionately.

-J. Benjamin Earl (O.K. Earl Corporation)

I really enjoyed working with Matthew throughout this project and found him to be professional in handling the business matters, but with a nice, personal touch that made me feel I was working with a friend instead of an impersonal corporation.  The entire construction process was harmonious, and I attribute a large part of this to Matthew's handling of the issues and challenges that arose with promptness and grace.
