Mark A. Mitrovich
Superintendent Of Schools - Naperville Community Unit School District 203
The renovation portion of the $114.9 Million project was successfully completed one year ahead of schedule and within budget.

IHC was able to coordinate complex work under very tight deadlines and the quality of construction was within set guidelines.

Based on our experience, we can recommend IHC for building project needs. IHC’s team is professional, capable and responsible.
Dana Wishnick
Library Director - Chicago Ridge Public Library
The team at IHC walked us through every step of the process with extensive knowledge and professionalism, representing the library's interests and resulting in a successful renovation completed on time and budget.

I cannot imagine how I would have survived this project without the direction, knowledge, and professionalism of IHC.
Paul Dawson
Managing Director - Elgin Community College
IHC demanded a high level of safety during the entire building program. Your culture of safety provided a benchmark for all participants including your subcontractors to follow.

The attention to detail and planning has guaranteed our project will be completed ahead of schedule and significantly under budget. I can highly recommend IHC for any building project.
Joseph P. Murphy
Business Manager - Argo Community High School District 217
I have had the pleasure of working with IHC on over $110 Million of capital projects at both Argo Community High School and Moraine Valley Community College.

On all projects, IHC has demonstrated both the expertise and professionalism to make the jobs successful and to meet the owner’s needs. I would highly recommend IHC for future building programs.
Stacey Bachar
Assistant Superintendent for Business Services/CSBO - Aptakisic-Tripp Community Consolidated School District 102
I wanted to express our sincere thanks and gratitude for the amazing job IHC performed as the district's construction manager on our recent capital improvement projects saving the district approximately $5 million dollars.

IHC's staff, both in the office and in the field, did a great job ensuring that we stayed on budget while still incorporating all of the important design elements and kept all of the work on track, particularly with a very aggressive summer schedule and 4 buildings under construction at the same time.
Scott Clay
Superintendent - East Maine School District 63
We have done two large projects with IHC and have been quite pleased with their work. They kept us informed throughout the process and were always willing to answer questions and listen to our concerns. I would definitely choose IHC again in the future.
Dr. Dan Coles
Superintendent Of Schools - Wauconda Community Unit School District 118
IHC is a cut above the rest. The company’s professionalism, expertise and work ethic never disappoints. Wauconda CUSD 118 is grateful to have IHC as our Construction Management firm!
Dr. Jean Sophie
Superintendent of Schools - Lake Bluff School District 65
IHC worked in tandem with our architect throughout the construction process which made it seamless from a School District point of view. They were always available to answer questions quickly and advocated for our district at all times.

IHC is awesome to work with and we will continue to use them for upcoming projects.
Kimberly Coughran
Director - Brookfield Public Library
From start to finish, everyone on staff from IHC including the Project Manager to Site Supervisor were responsive and cooperative.

Our project has even featured a community partnership with the Brookfield Zoo, that sees IHC staff going over and above the call of duty on a regular basis by transporting faux life-sized zoo animals, back and forth to the zoo for repainting and replacing back on the Library's site.
Daniel Ford
Director of Buildings & Grounds - North Palos School District 117
Every Site Superintendent, Project Manager, or Engineer I have worked with has been professional, responsive, and easy to work with.

Sometimes in order to maintain a schedule, double shifts were worked to ensure substantial completion to not interfere with the opening/start of a new school year. I would recommend IHC as a Construction Manager to any client.
Andrew Duren
Executive Vice President - Moraine Valley Community College
IHC was a valuable partner in our $97 Million program. Your ability to coordinate complex work under tight deadlines was impressive and the quality of construction is excellent as well. Your team approach to program solving built trust, but being able to rely on your forces when something that just needed to get done was a benefit beyond description.
Ellyn Wrzeski
Superintendent of Schools - Woodstock Community Unit School District 200
IHC is to be commended on the outstanding job your firm did on the $112 Million Building Program. The schedule barely allowed 16 months for the design and construction of this large school which required fast-tracking the project.

The school was successfully completed on schedule and within budget. Based on our experience, Woodstock can highly recommend IHC for building project needs.
Susan O. Center
Assistant High School Principal - Round Lake Area Schools Community Unit School District 116
IHC’s Construction Superintendent was an incredible help to us this weekend. He worked outside of his work hours and responsibilities to help resolve a power outage before our first home football game.

I cannot tell you how much this, going above and beyond, was appreciated. Even though his actions may seem simple, they were very significant to us.
Dr. Jerry O'Shea
Superintendent of Schools - Marquardt School District 15
Marquardt SD 15 has had the privilege to partner with IHC on a number of projects, most notably the Performing Arts Center at Marquardt Middle School. The 33,000 SF facility features a 500-seat auditorium and STEAM lab, as well as rooms for art, choir, orchestra, and for the first time, drama.

Through every stage of the project, IHC kept the needs of our school district, students, and community at the heart of their work. They were accessible, communicative, and flexible and we are grateful for their partnership.

🎬 A Day of Caring, Hollywood Style! 🌟

This past Friday, IHC was proud to partner once again with the Association for Individual Development (AID) for our 2026 Annual Day of Caring!

This year's theme, "AID Night at the Movies," brought a little Hollywood magic to the O'Shea Center! From music and dancing to temporary tattoos, red carpet photos, and delicious food, the day was filled with laughter, smiles, and unforgettable memories.

This annual celebration is something we look forward to every year, and we are grateful for the opportunity to spend time with AID's incredible clients and staff.

We're proud to continue this meaningful tradition and create lasting memories with the AID community year after year! 💛
