Computer Training & Support Services, Inc.

Founded in 1991 by Bill Marks, Computer Training & Support started as a small company to provide individuals one-on-one on-site computer tutoring/training. In 1993, our company was written up in the Pioneer Press pointing out our presence to new computer users. Since then, we have been recognized by various newspapers and media. At the beginning of 1995, when computers gained popularity, CT&SS started to offer classes in local Park District Facilities bringing instruction into the backyards of homes and small businesses. To this day, CT&SS continues to offer both one-on-one on-site hands-on tutoring plus affordable small group classes in Chicago land Park District facilities ranging from $25 - $175. Our classes are offered primarily to the beginner but also to the intermediate and advanced computer user. Everything we offer provides repetition and challenge to enlighten computing in the present era.

Bill went above and beyond. In 2 days he helped me find a new computer for my needs and he got it up and running and spent time helping me understand it. Would definitely hire again and highly recommend!

Not only fixed my computer but provided helpful advice on a number of other issues including desirable features for a replacement computer. FOLLOW UP: I purchased a new Dell Windows 10 computer with specs recommended by Bill Marks. I also hired him to help me install it as well as simplify and move additional equipment. We did encounter a couple of issues, but Bill was able to solve them in minutes whereas it would have taken me hours. His depth of knowledge of both new and old computers is unsurpassed based on my past experience using tech support sources. I would strongly recommend using Computer Training and Support Services!!!

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
