"Jeff and Andrew are the best partners we’ve had as a business so far. They’ve used their extensive expertise to guide us through two difficult and stressful office moves. More importantly they understand our business, our culture and our objectives, which means they’ve been able to find an office needle in a real estate haystack, twice. I would thoroughly recommend trusting them with your business. Unless you’re a competitor of ours – in that case, they’re terrible.” - Matt Harper, Managing Director, The Marketing Practice
