Misty’s practice is dedicated exclusively to representing nonprofit and tax exempt organizations, including forming tax-exempt organizations, preparing organizational documents and policies, preparing applications for federal and state tax exemptions, and advising on issues regarding the operation, management, and taxation of tax-exempt organizations, with a focus on private foundations, including complex activities such as program related investments and international grantmaking and operations. Her practice also includes addressing sophisticated tax issues.

The legal advice that Misty provides is grounded in experience.
