Justin, I wanted to drop you a quick note to say thank you for all your support with helping us find our perfect office space. You were extremely professional to deal with and really got to know who we were as a business and therefore what sort of office space would work for our people. I really appreciated how connected you were and how you kept us really well informed throughout the whole process. Thank you once again for making the experience an easy one, it really was great having you support us. I couldn't recommend you highly enough.

I had been working with a few other agents and brokers for a while, but found the right spot with Justin after just one phone call and one round of viewings with them.Justin was awesome to work with from the get go, totally getting the brief and presenting us with a number of great options at great rates. Totally recommend Justin you’re looking for a new space!
