Freelance Fashion Designer/ Pattern Maker
Stefan has done an exceptional job in diagnosing my computer problems and providing the best solution. He is extremely efficient and determined in his work and gave me valuable insight into where and why it all went wrong. He also successfully retrieved my personal data from a hard drive that has seen better days! I will definitely be keeping Stefan's contact details.

Licensed Real Estate Salesperson at Town Residential
Stefan is undoubtedly an IT guru. He worked with my company to supply general IT support and consulting. I also hired Stefan to recover a failed hard drive that had a huge amount of personal data on it. He was a lifesaver! Not only did he recover all of the data, but he did it in one day and at a fraction of the cost that the drive manufacturer was going to charge.

He is a respectful, discreet gentleman, and I feel absolutely comfortable inviting him into my home and office.

Stephan is very knowledgeable in his field. Over the years, I have wasted a lot of money on IT people that didn't fully know how to set up my work space. I only wish I knew Stephan then so I could have used him instead. He is dedicated and passionate about his work, as well as a perfectionist.

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.

Associate Broker at Oxford Property Group
Stefan not only fixed our computer problems, and networked our printers, but also taught me how to be the office manager/IT Admin, which gave me a little bit more job security, and a slight raise. He also had all of our real estate agents come in for a free tutorial on how to scan to email, edit PDFs, back up files, etc... and gave advice on how to protect ourselves and...more
Neil Zwiebel, D.P.M.
Podiatrist, Park East Podiatry
I highly reccomend Stefan for IT work. I have used him on many circumstances from setting up a network to restoring an infected computer to minor computing issues. His work is great. He took a poorly set up network by another so called "IT professional" and converted it into a reliable network. He has always made good reccomendations and is very personable.
