Serving the Inland Empire and Riverside since 1974.  Massaro and Welsh

About Us

Massaro & Welsh was founded in 1974 by Richard O. Massaro and Paul T. Welsh in San Bernardino, California.

Since its founding, this firm has prized quality above quantity, integrity and a good reputation above profits. We are licensed professionals, who not only have the theoretical knowledge, but have the practical experience as well, to perform work which is economically justified and feasible.

Massaro & Welsh is a multidisciplinary firm offering in-house capabilities and professional services in the fields of engineering (civil, transportation, sanitary, and structural), planning, land surveying, and construction management.

The services rendered by Massaro & Welsh cover an unusually wide range. When requested, the firm will do the normal planning, design, and construction supervision jobs. We can do "turn-key" jobs, where-by design and construction and start-up are our responsibility.

Massaro and Welsh places a high priority on innovation and integration of new technology and, above all, is sensitive to the real needs of its clients. The firm's small size assures that each client receives the personal attention of its top managers. For uniquely complex projects, Massaro & Welsh can cooperate with independent consultants and specialty firms which have the required expertise or which are local to the job site.

Through the years, Massaro & Welsh has developed a close working relationship with a number of highly qualified associates who supply specialized knowledge and expertise when needed.

Massaro & Welsh provides services throughout the State of California, including San Bernardino County, Riverside County, and Los Angeles County.
