Client Testimonial

George Lauro Portrait

I was very impressed with the F-18 Process. It helped all of us on the board understand what we could expect from our top candidates if and when they became the CEO. It was also a great indication of the commitment of our top candidates, based on how they prepared for this event.

George Lauro, Board Director, Sensera
Thomas Fallon Portrait

I was very impressed with Lonergan Partners. Mark brought clear and practical insight into our business and its corresponding challenges. Most impressive was Mark’s honest assessment of what we needed and his candid review of the many candidates he brought into the discussion. I am certain I will take advantage of his services in the future.

Personal History

I’ve been on both sides of the table

I’ve been very lucky in my career, join­ing a Sil­i­con Val­ley tech­nol­o­gy com­pa­ny right out of col­lege and help­ing grow that com­pa­ny (Tym­net, a pio­neer in data com­mu­ni­ca­tions net­work­ing) into a glob­al operation.

Through my twin careers as both an oper­at­ing exec­u­tive and a search pro­fes­sion­al, I’ve been for­tu­nate to work with some of the great lead­ers in the his­to­ry of Tech­nol­o­gy: John Mor­gridge (CEO & Chair­man, Cis­co), Gil Ame­lio (CEO, Nation­al Semi­con­duc­tor) Fed­eri­co Fag­gin (Intel), David Lam (Founder, Lam Research), Mike Hack­worth (CEO, Cir­rus Log­ic), Don Valen­tine (Founder, Sequoia Cap­i­tal) and many, many others.

The right stuff

While the styles of these lead­ers dif­fer great­ly, they seem to share a com­mon set of prin­ci­ples that dri­ve com­pa­nies to become great — they believe in their peo­ple, they expect the best from every­one in their orga­ni­za­tions, they’re pas­sion­ate about inno­va­tion, and they strive to become the best in the world at every­thing they do.

This is the great secret of the Sil­i­con Val­ley — if you shoot high enough and demand the best, you can become a world leader in the tech­nol­o­gy market.
