“Jonathan Stein and the team of consultants with Tech Underground have provided Big Brothers Big Sisters with an extremely high level of technical support at very reasonable rates. From ongoing network maintenance to staff training to e-mail hosting, Jonathan and his associates have been able to respond to all of our technology needs. We, as an organization, feel secure knowing we have such an experienced support system at our disposal.”
—Maile Balch-Clasen, Program Director – Big Brothers Big Sisters of San Francisco & the Peninsula

“And finally, THANK YOU for your help in getting CAN to this turning point. It has been a long, intense and sometimes mind-perplexing process, and I know we don’t even realize the half of what you did to get us here.”
