What Departments Say About CLS

Jerry H (Realtor)

"Talk about a rapid response! I think your team returned the credit report within 15 minutes of receiving the request INCLUDING the time we spent on the phone. Very impressive!"

Bob Tucker

"CLS has been a great resource for the Give Something Back Foundation for over five years. CLS conducts background checks on our mentors who will be guiding/ mentoring high school students in our program. CLS is priced very reasonable and the turn around on the background checks is usuall 1-2 days. We appreciate our partnership with CLS Background Investigations."

Donna Johnson

"CLS has provided background checks for us for many years. They are experts in their field, they are very dedicated as well as reliable and pay much attention to detail. They have provided unparalleled customer service and are also great problem solvers. We could not have hired thousands of reliable field reps without CLS’s support. They have spent many weekends and after hours working with us on many last minute requests. Their commitment and expertise in their field is outstanding."

Diane Seiler (Zigrossi)

"I have had the opportunity and privilege of knowing and working with CLS/ Makton Investigations for several years as well as recommending their services to my client base. Their knowledge and expertise in the areas of background investigations and law enforcement are a valuable asset to any company who requires that next level of security in their hiring practices. I would strongly recommend their services."

Becky O’Neill

"Dan Skoczylas, of CLS Background Investigations, is probably one of the most dedicated, hardworking and honest individuals I know. His integrity is in a league of its own. I am a real estate agent and met Dan in 2005. I have utilized CLS services a few times to perform background investigations on potential tenants that will be placed into my rental properties. I was thoroughly impressed with his attention to detail and his care to make sure my client was protected. I have the highest amount of respect for Dan and CLS Background Investigations and I would refer CLS to anyone time and time again."

Tom G. (Realtor)

"Congratulations are in order for CLS/ Makton President Carol Skoczylas. Carol was recognized by the Business Ledger at their Entrepreneurial Excellence Awards presentation in the category of “Innovation”.I want to offer to serve as a reference if you ever have a potential client who may want to talk to a current client of yours. It would be a privilege and pleasure to share my experiences with your outstanding service and responsiveness."

Ross C.

"I really like CLS-from the interface, to the outstanding level of service you have personally provided time and time again."

Dave O’Connor

"CLS Enterprises/ Makton Investigations are the best. I have had occasions in which I required the assistance of a private investigation firm to perform a variety of investigative functions on behalf of clients. The agents at Makton were always receptive, professional, and thorough with all aspects of their assignment. There are many investigation firms available. CLS/ Makton far exceeds those firms in their skills and commitment to doing the job and doing it right."

Renee S.

"Awesome…..very user friendly system…thanks so much!!!"

Ranae Damaschke, Shadow Lakes II Association

"I would just like to say that I have used CLS Background Investigations for 2 years now. I have found them to be very easy to work with, very thorough and have actually provided details that made my company change their minds on some hires. I will be using them over and over again."

Bob T.

"Thank you for embracing the “Service After the Sale” motto. A big thank you is in order-keep up the good work!"

William Doherty

"Prior to utilizing CLS, the Roberts Park Fire Protection District Board of Fire Commissioners conducted background checks for new employees. The process was time consuming and lacked consistency. CLS gives the fire district a consistent, thorough and professional pre-employment screening that is conducted according to current laws. We are extremely pleased with the service provided by CLS."
