Fractional services, 
Full-time partnership.

We believe that financial health and success are foundational for any business and that good foundations aren’t built alone. Our mission and values reflect that.

Cornerstone’s Mission

Educate

We believe every business benefits from a deep understanding of their financial position. In fact, we believe this is essential for your company’s financial health and long-term success. Financial education and literacy are for everyone.

Equip

We partner with business leaders helping them to build their business with intention. Whether you wish to scale revenue, establish new markets or simply reclaim focus by outsourcing finance & accounting, we’re here to help.

Serve

No one knows your business better than you do. We’re here to help you make the best financial decisions for your business, ease your workload, and give you peace of mind. Let us handle the finances so you can focus on the business.

Community Servants

At Cornerstone, we measure our success by our ability to serve our community. We strive to be partners and servants not only to the people who work with us, but also to the people around us. We invite you to join us as we move to fight homelessness and addiction in our local communities across New England.
