How Rory describes Macmillan Keck:

We are design engineers.

We build things for the long term, designed to last. They may be laws or public private partnerships or commercial agreements. They are each tailored, almost never repeat jobs. Each time we push the boundaries of our and our clients’ knowledge. We draw on our experience and push it outward to meet the design needs of the client – be they competition, innovation and investment in the ICT sector, or a long-term commercial venture in a submarine cable landing station that achieves governance and competition, rapid roll-out of digital financial services.

Richard on Rory:

Rory’s depth of knowledge, combined with his ability to never lose sight of the big picture, gives him an almost uncanny ability to anticipate the future. His belief and passion make all of us better.

Client testimonial:
When we were looking for a firm to help draft new data protection legislation, we were originally looking at larger firms. But after a conversation with Rory, we realized that no one else we’d spoken to understood the possibilities and the challenges like he did. So we ended up going with Macmillan Keck. Which proved to be the best decision we’d made that year.
