Why Castle

The culture we build inside the agency is the one our clients meet. Here is what partners across Boston and beyond say about working with the Castle team.

Castle has been a valued partner to Deloitte for more than 15 years. From the senior-most level on down, the Castle team demonstrates a commitment to our brand, our business and our competitive position. As managing partner in this market, I appreciate Castle’s ability to support our visibility and thought leadership. They work seamlessly with our internal team to deliver results that make an impact. They are never satisfied with the status quo and are always looking to raise the bar in our work together.

The incredible thing about working with your Castle ambassadors is the ABSOLUTE trust I have in you. Castle thinks about all the issues in advance and plans accordingly. You anticipate all issues that arise. And you interact with my customers in the most professional, courteous and gracious manner I’ve ever seen from ANY service organization. I hope you’re getting the idea that I can’t gush enough about your performance.

Castle was the force that built the Care.com brand in Boston. From networks, to speaking engagements, to press to board seats. Castle has been a strategic partner every step of the way. When I arrived at MIT's Martin Trust Center for Entrepreneurship and we had to develop a brand marketing and PR strategy, Castle was the first call I made.

Co-founder, Care.com
For nearly 30 years, The Castle Group has been a pillar of Boston, lifting up the stories that highlight the work of our people and communities, our local businesses and organizations. Without The Castle Group’s expertise, so many of our community’s stories—like the one behind The Embrace—would not get the regional and national attention that they deserve. That’s why I’m so grateful for Sandy Lish, Wendy Spivak, and the entire Castle team for all of the work they do to highlight everything that makes Boston a city for everyone. We’re so grateful for everything The Castle Group has helped us accomplish so far, and we’re looking forward to our continued partnership.

Everything went off without a hitch and the entire weekend was perfectly planned. Castle's attention to detail made the difference.

I have worked with Castle for years on very challenging subjects and topics. I find them to be strategic thinkers with great implementation and follow-up skills.
