On behalf of the AMA, thank you for the significant contribution made by REX Electric and Technologies to the AMA Interaction Studio at MATTER. Your participation and expertise has allowed us to create a dynamic space that connects physicians with entrepreneurs and the broader health care community, both in person and virtually, to test and advance new technology.

~ James L. Madara, MD, CEO, American Medical Association

I had the pleasure of interacting with your electrician today.  He graciously came back to our office and explained what he did. He then showed me and other staff where to look for easy fixes for our problems.  I can assure you that those of us in the office will certainly recommend REX Electric for future electric work.


~ Moya Belcaster, Senior Manager, Finance & Accounting, Association for Corporate Growth, Inc.

I wanted to take a moment to thank Rex Electric for the excellent job you did.  REX personnel were very responsive to every issue and detail of the project.  And they were excellent with helping to drive the schedule and coordinate with other trades.  As the general contractor, we understand that our success is due to the excellent performance of our major subcontractors on this project.



~ Bryan Kreuger, Vice President, Senior Project Manager, LEED A.P., Chicago, Illinois

We would like to send a heartfelt thank you for your help in making our new downtown office such an amazing space that reflects the culture and core beliefs of our company.  We truly appreciate the efforts that REX Electric contributed to this project, and it is only with your help that we could have brought this vision to reality. We look forward to the continued growth of our relationship and to many more successful projects in the future.


~ Chad Correll, Executive Vice President, Executive Construction INC.

I am writing to commend the professionalism and quality of work performed by your employees. (REX personnel) did an excellent job in working with Ragnar Benson to maintain the construction schedule and complete the project with little or no punch list. I would be happy to recommend REX Electric to any future projects Ragnar Benson would be a part of.


~ Chris Grzynkowicz,  Superintendent, Ragnar Benson Construction, Park Ridge , Illinois

Despite many hurdles, (REX personnel) remained patient and exuded professionalism throughout the effort. He was excellent and is a primary reason why I’d call REX in the future for any new wiring or rewiring efforts here.


~ Chris Munger, Senior IT Manager, American Academy of Periodontology, Chicago, Illinois

I would like to thank you for the professionalism REX portrayed in taking care of Oak Park Hospital while handling the switch change-out. Undoubtedly, REX realizes the importance of seeing a job being done with the utmost precision.


~ James Richardson, Facilities Manager Director, Oak Park Hospital, Illinois

We lost a 400 amp feed to a penthouse. Early Saturday morning, (REX personnel) was at the property within 45 minutes of my call. By the time we were powered back up, he had the fuses and main fan coil under control. You have no idea how many headaches I was able to avoid thanks to him.


~ James Brady, Chief Engineer, GlenStar Properties, Chicago, IL

(REX personnel) made quick and easy work of what basically would have been my worst nightmare.  We are now not only “operational” again at home but actually even better off than we were before. Thank you again for helping out.


~ J. Corbett Marx, Vice President, Midwest Region TRANSWESTERN

(REX personnel)’s attention to detail, customer satisfaction and error free work is something to be proud of. The pressures of the project were extremely high with a short weekend window and multiple trade contractors. Yet, (REX personnel) were very cool, calm and collected. They understand our needs, have excellent communication skills and always live up to our expectations.



~ Dave Mucha, Vice President - Facilities , Federal Home Loan Bank of Chicago

Your foreman/electrician is by far the best tradesman who has ever worked at Casa Italia. He is always looking for the most practical and economical ways to complete a project without sacrificing quality. He is amazingly punctual, professional and hard working.  Your purchasing agent also performed in an exemplary manner. He handled an extremely time-sensitive matter with skill and speed.  I can’t tell you how fortunate I feel to be doing business with REX Electric.


~ Paul Basile, Director General, Casa Italia, Stone Park, Illinois

(REX personnel) took issues to heart, overcame what seemed to be insurmountable challenges, and saw through them to the end. The degree of coordination, quality of work, and overall good attitude expressed on a daily basis by (REX personnel) made this project a success.


~ Matt Stewart, Senior Associate, Syska Hennessy Group, Los Angeles, CA

We had a small emergency job. REX sent help within an hour of my call.  We were impressed with (REX personnel)’s professionalism, dive-right-in-and-help attitude, attention to safety & proper procedures, and diagnostic & troubleshooting abilities. REX Electric helped us when we needed help, and that counts for a lot.


~ Mark D. Anderson, The John Buck Company, Chicago , Illinois

Your electricians did an extraordinary job working in coordination with ECI. REX’s ability to provide manpower for the operation, assess the situation and work with us on a recovery plan deserves recognition. Your workforce was highly professional and knowledgeable and your efforts should be applauded!

~ John A Lindquist, Superintendent, Bear Construction, Morton Grove, IL.

(REX personnel) came up with a great plan to both meet our needs now and in the future.  We are once again satisfied customers of REX Electric.


~ Sean P. Hicke, Operations Manager, NEC Sphere Communications Inc., Lincolnshire, IL

Prime recently moved to its Chicago headquarters to a new and better space, and could not have done so without (REX personnel)’s efforts. In the 11th hour, we had less than a month to plan and execute the entire move. The most beautiful part is that REX was able to execute this work in the three-week window that we were left with.

~ Steve Crowley, Prime International Trading, Ltd., Chicago, IL
