What people say?

Stefan Leipold is — by far — one of the most valued resources I have found. As an freelance consultant, I depend on my capacity to use all forms of media flawlessly. Stefan has managed to cure computer problems no others could solve. He is fast and I would recommend him without reservation.

By coincidence I learned about ProSysCo. Stefan Leipold, the owner, did not only answer the phone but made himself available right the next day. He spent several hours to solve and explain the problem. And charged less than he could have. Stefan Leipold seems to combine a wealth of expertise and reliability with strong work ethics. His personable nature is a pleasant add.

To say that Stefan is 1st rate is an understatement.. His skills are superlative and he makes the process painless.. I would recommend him on a personal level for the home user/ business or for any type of business that is reliant on computers!
