Since we hired Cornerstone LA to handle our campaign of pay per click as well as to create and manage our new Web site, the number of clients has increased 50% every month. Currently, there’s an average of two new clients a day that find us by Internet. We also receive congratulations for our Web site all the time.

Customer service is impeccable, they always answer in a few hours and they promptly take care of all requests.

Thank you Cornerstone for the excellent job you do!

I had many doubts about the effectiveness of businesses by these means but since I was contacted by Cornerstone LA and their reasons about increasing our clients and be known and visible in the market at an international level made us think on the possibility of dealing with some hesitation about the effectiveness of the contacts.

The attention this company provides is magnificent, they take care of any doubt or any change we have to do to the campaign with no objection at all unless we are mistaken and they let us know it with solid arguments and absolute knowledge.

Local and people from some other countries who are interested in our programs have contacted our institute LEARN INTERNATIONAL LANGUAGES with offices in Cali, Bogotá and Medellin, they are interested in learning about us and we have a large data base but that’s not it, we have already enrolled new clients.
