"I know this last minute med gas master alarm panel was a scramble to put together, but your guys were phenomenal in staying out of the way of staff and patient workflow yesterday ...  they worked to keep everything moving throughout the Imaging and CH corridors. That did not go unnoticed.

With all the issues in getting this CH project finalized, Lemberg has been fantastic to work with. I only wish I could say that about all the other subs on the project. Your team always goes above and beyond and that is much appreciated."

Lemberg employees have a good demeanor, they are respectable and lastly, they have an awesome work ethic...Lemberg ended up being one of the best subcontractors we had on this project and one of the best subcontractors I've worked with in general. Keep up the great work!"

"Lemberg has a team that definitely sets the bar high in our industry. The level of detail and response is incredible. Lemberg almost always provides a solutions attached to any question which allows for the design team to accelerate the process. The internal communication that Lemberg had on this project was also a key to our success. Through any stage of the project the office and field management were equally aware of the current state of the project and all the details, which gave VJS the ability to reach out in multiple directions for solutions if needed. Adam and Tom did an outstanding job along with many other craft workers joining the process."
