This month marks a tremendous milestone in RTM’s history, we are celebrating our 40th year in business. Starting out in 1981 as a 3-person firm offering mechanical engineering services to local clients in the Midwest, RTM has grown into a national 200-person firm with licenses in all 50 states, and offering a wide range of services from MEP and civil to commissioning and other specialty services like arc flash and refrigeration. We have built our reputation upon our commitment to becoming a partner to our clients, and pride ourselves on keeping those local relationships strong for years to come.

To help celebrate, we are looking back at some of the memories that have been made over the past 40 years, and look forward to more memories to come!


Giving back to our local communities is important to the team at RTM. Over the years we have volunteered time at food pantries and kitchens, participated in fundraisers and food drives, “adopted a family” for the holidays, volunteered with the Special Olympics, and more.
Today we’re looking back on how we’ve given back.

“My favorite office prank was when Amanda went on vacation, I booby-trapped her desk snack drawer with a wireless door contact alarm. When she went for a snack, the whole office, and especially Amanda, jumped when the alarm went off. She did it at least two more times with the same result because she couldn’t understand what was happening. Of course, somebody left a basket full of 3-hole punch chads from the big printer all over my desk and chair when I returned from my next vacation.”

Our Chicago office, which officially opened its doors back in 2011 started an annual tradition of holding a beach volleyball outing at North Avenue Beach. After a few hours of competitive spirit, the team heads over to Castaways to enjoy a few drinks and some appetizers.
Here are some fun shots of the team during a 2015 outing.

Sharing some fun holiday cheer across the offices over the years. We’ve done it all from ugly sweater contests, cubicle decorating, Thanksgiving potlucks, Halloween parties and pumpkin carving, gingerbread house making, and more!

“In 2010 coming out of the recession, Tony and Doug had been trying to get in with a local property manager in Schaumburg. We got our first chance and they scheduled Sheetal and I to meet with the property manager, as he wanted to meet the engineers who would be working on the projects. Tony prepped us both that this man would be extremely difficult, but a great opportunity for RTM. When we arrived to the meeting, the man said, “Wow female engineers! Maybe someone will finally listen to my team, and we can get things done right!” That day started a 6-year relationship as the go-to engineer for that property group.”

Looking back at a 2014 year end party we held, where we brought the casino to us. What a fun night!

Back in the day, when our Chicago office was

small enough that moving meant rolling your

office chairs down the street to the new office!

Showing off some of the fun times our Milwaukee office had back in 2014: holiday lunches, boat cruises, Summerfest, and getting a chance to meet some of the other RTM office members.

A fun team-building event where groups of four were given a pile of materials in which they had to build a floatation device. Then, one member of each team had to “sail” it out to the buoy and back.
…and then the real boats were brought out!

“I joined RTM back in 2004 when there were only 10 employees in the Schaumburg office. Throughout my 17 years at RTM, work has been challenging at times, but always exciting in the sense that I have been able to learn and develop new skills to problem solve various issues. I feel fortunate to work with a great team and supportive management. Outside of work, we have had the opportunity for multiple team bonding events such as dinner, boating, golfing, painting and cooking. I look forward to continuing my journey with RTM in the years to come.”

Trinh Tang | Project Engineer

“One of my favorite RTM memories happened on the first day I joined RTM, The day we had finished signing the paperwork joining Applied Engineering with RTM. That moment was memorable enough by itself, but then the South Barrington (now Schaumburg) office had a pizza party out in the parking lot to welcome us. It was nice to get to know everyone better and finding out what a great culture RTM has. At this welcoming party, I had a long conversation with Ramesh and got to know him much better as well. Ramesh reminded me of my grandfather, rest his soul, who was one of the kindest persons I’ve ever known. After that conversation, it solidified what a wonderful family the Mirchandani’s are and what a great decision I had made to join RTM.”

Scott DiGilio | Principal, Civil

Some memorable times from one of our first multi-office parties, where members took part in learning to cook various dishes together.
