Erdelyi, Peter Tibor DBA Peter T. Erdelyi & Associates, Inc. Engineer

In 1974 Peter Erdelyi started working as a professional engineer in California. In 1978 he became one of the initial co-founders and owners of Erdelyi, Moon, Mezey and Associates, a partnership of structural engineers. Subsequently the name was changed to Erdelyi, Mezey and Associates and to its current form, Peter Erdelyi and Associate, in 1988. The company continued working out of its original location just south of Beverly Hills until its relocation to a new office building in December, 2009.

In 2005 Sayed Attaalla joined the firm and currently holds the titles of Vice President and Chief Engineer. The arrival of Sayed marked the beginning of a period of rapid growth in company size and an increase in the number of concurrent projects handled. With Mr. Attaalla’s invaluable contribution, our team has designed many highly complex projects in the recent past.

The end of 2009 found the company in a brand new, upgraded location in West Los Angeles on Sawtelle Blvd in the immediate vicinity of the Los Angeles Department of Building and Safety.

To present day, after more than three decades, Peter Erdelyi continues to actively supervise projects from launch to completion on a daily basis, although he lost count of them somewhere around 10,000.
