Apple, Inc.

"In all my work with Apple's partners, I have never met one more dedicated to knowing Apple, Apple products and Apple-centered solutions, than Pam Lefkowitz. She is tough, tenacious and gets things done for Apple, her customers and her partners. If you have challenges with Apple technology, I highly recommend Pam Lefkowitz as a consultant."

Todd Lohenry,

Ballard Desai Miller

“We have worked with many Mac consultants over the years and Pam and her organization are highly superior to all the rest. I recommend her without hesitation to anyone seeking a knowledgeable Mac consultant who makes sure that products work correctly before you install them, and who can help you recover in a timely way from those rare technology glitches that can completely undo your organization.”

Delta Direct Marketing

"Pam Lefkowitz is that rare breed – a savvy computer pro who can talk in plain, understandable English instead of computer-ese to technophobes like me. She's amazingly responsive and helpful, and her willingness to do whatever it takes to solve a problem has saved me more times than I care to recall. If it's possible to solve a problem on the phone or via email, she'll do it that way; if she needs to come to my office, she does that. She's practical, too, and the solutions she recommends make sense. She knows her stuff, she's generous with her knowledge, and she's great to work with. I can't recommend her too highly."

Susanne Southwood, President
