Our Story
Founded by a husband and wife. Run with the same attention to detail ever since.
Ahmad Ghaderi, along with his wife Susan, founded A&S Engineering in 1988. Over our 30+ year history we have established a national reputation as a leading design firm. Our practice has diversified over the years — but our firm attention to detail and commitment to quality design have not changed.
Ahmad leads the firm as President. Susan manages its day-to-day financial and HR operations; she studied accounting and management at Michigan State. Our longest-serving engineers have been with the firm for more than 15 and 17 years.
[PLACEHOLDER — 2–3 sentences on why Ahmad & Susan started the firm and its first projects / clients]
“Their knowledge of the area and regulators at the city provided significant assistance in reducing the entitlement process time, which saved a number of months during the early development process.”
“In addition to handling the A/E portion of the project, A & S Engineering handled all work related to the entitlement process through final approval of the building permit … I would highly recommend A & S Engineering for your entitlement and A/E services.”
Our Results
Razing and rebuilding for national brands.
Gas stations, convenience stores, restaurants, car washes and retail centers — plus work for major developers of office buildings and public storage companies.
