Tony Holowitz: Chief Old Dog

My name is Tony Holowitz and I own a computer training business based in greater Boston – Arlington Massachusetts to be exact. Since 1998 I’ve been working with individuals and businesses teaching them how to do more with their computers. I offer one-on-one training, consulting and web design services.  On this website you will find more than 70 hours of free computer training videos, the vast majority of which were produced and created by me. My free computer training classes and tutorials are available 24/7/365 and no registration is required.

It wasn’t too long ago when a lot of people were losing their jobs and out of work. It was at about that time I decided people needed a break, and that’s why I decided to offer all of this training for free. In this difficult economic climate, people needed help developing the computer skills they needed to improve their ability to get a new job or even start a business. Providing this free computer training is my way of giving a little something back. I decided to provide assistance to the world in the best way I know how…teaching!
