Our 10,000 square foot, state-of-the-art laboratory, and highly skilled team of

Engineering Experts are able to provide comprehensive design and engineering services for a wide range of industries.

BEAR experts have extensive multi-state

trial and deposition experience.


Founded in 1986, our engineers have

consulted on hundreds of critical,

high-profile projects including the

Alaskan Pipeline, the Golden Gate Bridge,

the BP Horizon oil spill in the Gulf of

Mexico, the Milwaukee Brewers Stadium

roof collapse, the Lan Chile airplane fire

at the Miami airport, and the San Bruno

pipeline failure, among many others. 

BEAR engineers also develop a wide range

of specialized products, from cauterizing forceps for surgery that prevent tissue

burning to powerline detectors for

cranes and lifts to high strength frame

and body components for automobiles

and trucks. 

Our investigative approach as problem

solvers covers every angle. We seek to

find out what happened, why it happened,

who or what caused it, and all possible preventative solutions - communicating our findings to our clients in a comprehensive

and meaningful way.


Our founders, Glen Stevick, Ph.D., P.E. and Philip Alei, Ph.D., P.E, 

together with our senior engineers,

David Rondinone, Ph.D., PE., and 

Derek King, M.S., P.E. and material/mechanical engineer

Mingxi Zheng, M.S., P.E.

have over 85 years of combined experience, successfully working on cases and research projects, from

failure analysis and product defects

to patent litigation and prototyping.

Our team of experts with extensive experience in mechanical, electrical and materials engineering provide unique solutions.
