Pros
It's rare to find a branding /design agency that truly values the work they create, and the companies they partner with. UI carefully considers the clients they produce work for, ensuring the project is challenging, the product/service is unique, and that the clients are truly excited to work with them.
-----
The Capitol Hill location is a rare find, and a nice perk.
Cons
You're working with a team who is dedicated to greatness, so sometimes the days can be long.
