"Konstantin Kostadinov has been providing services to our company for the last year. Our computers are “mission critical” components of our firm. It is no exaggeration to say that his commitment, technical know-how and strategic understanding of IT have kept our business in business. If you’d like to discuss how Konstantin helped us avoid catastrophe, don’t hesitate to call. Needless-to-say, I recommend Konstantin with the highest marks. You’re fortunate you’ve found him."

"Konstantin Kostadinov has been associated with the Lake Forest Symphony as our IT Consultant for the past several years. We do not know what we would do without him. He is reliable, always ready to attack our problems with immediate solutions, completely trustworthy, friendly, and an IT savior. He has been available on the phone to walk us through difficulties as well as via office visits, including evenings and weekends.Both of us have engaged Konstantin on repeated occasions. We would not go to anyone else, whether it be for solutions or for consultations about new hardware, software, and security. He has been able to do it all, increasing our productivity, saving us money, and giving us peace of mind. Who could ask for more?"

"When a friend entrusted me with Konstantin's phone number it was akin to being given a panacea for all my existing and future computer ineptitudes, woes, and learning needs. He has always been available without delay to solve any and all problems. With patience and at my pace he has taught me new procedures that enhance my use of my computer. When I needed a new computer he walked me through all the possibilities, apprised me of relevant advantages with each, without championing a particular brand. When I made a decision he installed the new equipment with alacrity. Security is having Konstantin's phone number and e-mail address in my address book. We may need to have him cloned if his business surges too much."

"Konstantin did a terrific job for Beacon Signs. Gave us great advice. Was quick on the execution, thourough in the work. Loved it!"
