About Ali

Ali is the kind of person who makes coming to work fun every single day. Not because of her charm, although she is very charming, but because she is an expert at getting to know the client’s business and making sure the agency is living up to, and surpassing, the client’s expectations. Ali came to SHS from H&R Block in 2001. She immediately made the creatives insanely jealous by flaunting the Gold Clio she won as part of the team that launched Block’s new logo and identity standards system in 2000. Ali is responsible for providing clients with strategic insights.
