What People Say

Testimonials

“We have worked with Abossein Engineering for more than 25 years. Alex and his firm are all very knowledgeable and easy to work with.

They have always been able to meet even the most aggressive schedules and still produce at the highest level.”

Bill Quackenbush

”We have been working with Abossein for over 20 years. Good consultants are an invaluable resource when designing a complex building, and Abossein Engineering has consistently performed at a high level of excellence. They have been great to work with, looking at cost effective alternatives to design solutions and diligent in coordination of their disciplines.

Abossein Engineering is my first choice of consultant because of their successful track record, their competitive pricing, and their commitment to meeting tight schedules. I highly recommend them.”

Donald Flynn
Managing Architect, American Property Development

“Abossein has provided integrated Mechanical, Plumbing and Electrical design services for us for multiple projects. All these projects presented unique challenges that Abossein handled exceptionally. Their people were actively engaged throughout the design and helped us anticipate and resolve design issues before problems arise. Most importantly, by providing a lead contact across all disciplines, they made things easy for me. I only had one relationship to manage, and can rely on Abossein to coordinate internally as necessary. We get the best of both worlds, small firm customer service combined with the varied expertise of a larger company.”

Jeff Reibman, AIA LEED AP
Weber Thompson

“From an electrical contractor’s standpoint Abossein is exemplary at getting our input to incorporate into their design. This is especially valuable on design-build projects because it gives us an opportunity to provide a complete product within the budget constraints of our proposal to the general contractor. This teaming effort by Abossein, our company, other subcontractors, and the general contractor allows for a smooth design process. In a world where most engineers simply copy and paste boiler-plate material Abossein does a great job providing cutting edge designs that still can meet your budget.”

Nathan Howat
Vice President, Blue Mountain Electric Inc

“Abossein Engineering has always been very responsive, both in their design and in their proposal efforts. They are very effective at balancing the end users needs with the contractor’s budget. Abossein is my first choice for electrical engineering firms.”

Shaun Hall
Project Manager, Safari Electric

“I have worked with Abossein Engineering for the past two decades and have had excellent working relations. Much forethought into each specific condition is done before they provide their expert advice. I have 100% confidence in their follow-up on any issues that come up during plan review or in the construction process. They are the MEP engineers of my choice.”

Howard Kimura
HG Kimura Architect, PLLC

“It has been a great pleasure to work with Abossein Engineering and on our seniors housing communities. I have worked directly with Gary Womack for many years now. Gary is a knowledgeable and thoughtful designer, and is considerate of our design intent. He is practical and creative, a real asset.”
