"Gregg Mallus, owner of Sonic, LLC, has been doing general contracting work at The Liaison Capitol Hill (previously known as Holiday Inn on The Hill) for over 8 years. He has undertaken large contracting jobs (drywall, sprinkler piping, store front repair and painting for installation of a 4 pipe system), restoration of a kitchen after a major fire which required 4 months to repair to smaller jobs (restoring guest rooms and meeting rooms after a flood, remodeling a business center to converting standard rooms into ADA compliant rooms. I use Gregg primarily because his prices are competitive, his work is done in a timely manner and especially if something isn't just right, he is quick to resolve the issue, which makes me a happy customer."

"Gregg,
I was a pleasure to work with you and your company. After 23 years in the electrical contracting business I can tell you we have never experienced a more over communicated project with clearly defined expectations and a performance schedule that was actually adhered to. You have renewed my faith in General Contracts, but I still believe it could be another 23 years before I get to experience this again unless it is a project with your company. I look forward to the next opportunity that our companies can work together.”

"Greg Mallus with Sonic LLC is the contractor for our office here at Steven R. Johnson, DDS & Associates and he has been the best contractor we have ever worked with!

He came in and fixed what other contractors had planned to our distaste and he had GREAT solutions for issues that were previously unresolved. He is always “Johnny-on-the-spot” with our practice; always staying on top of all of the issues within our facility. We have never experienced any problems with Greg or anyone else working for him. He brought with him a WONDERFUL team that was also very helpful with staying on top of everything that needed to be done.

Every idea he had worked perfectly for our office and we could not be more pleased with the outcome of his work! We would be more than happy to have anyone that wants to see his work come in and see our BEAUTIFUL new office.

Thanks again Greg for all that you have done!"
