Client Testimonials

To Whom It May Concern:

We have for more than 30 years used Ralph Rubinstein, P.E. and the Aquarius Consulting Group for mechanical engineering services on projects such as research facilities for Bell Laboratories, office and computer centers for AT&T, Continental Insurance and American Express.
Mr. Rubinstein provided valuable assistance in the design and construction of numerous projects. We have found him to be an experienced and practical engineer who goes the extra mile to insure positive results.
We unconditionally recommend Ralph Rubinstein to anyone with a difficult job that has to be accomplished on time and within budget.

Yours truly,
David S. Steiner, Steiner Equities Group

“I have worked with The Aquarius Consulting Group several times over the last few years on some challenging projects. Their service, responsiveness and technical competence on every project I worked with them on was exceptional. I have referred them to friends, colleagues and clients with complete confidence and I will continue to do so. I am sure I will be doing business with The Aquarius Consulting Group well into the future.”
