Additional Team Members

E&A carefully selects team members for optimum value and impact. Team members have held positions inside companies (financial services, technology, retail, manufacturing and educational institutions) and, therefore, have experience on your side of the desk.

When workloads and/or specific client engagements make it wise, we supplement our permanent staff through long-standing relationships with senior interim accounting specialists (typically CPAs) and accounting interns from local universities. E&A often partners with other professional service firms, including attorneys and CPA firms to deliver specialized services to clients. E&A's alliances with Vanessa Pollard CPA, a minority-owned, woman-owned, CPA firm, brings highly qualified resources to further deepen E&A's team and meet MBE/WBE requirements. Our close relationship with Schmidt Associates, CPAs also adds depth and experience to E&A’s ability to meet almost any client need.

E&A's capabilities have also proven useful to other CPA firms who turn to us for our expertise and ability to work side-by-side with them. They frequently refer clients needing help with audits, reviews and expatriate taxation. Plus, team members speak to and are published authors on business issues for the public and other members of the profession, as well as serving as adjunct faculty at several local universities and colleges.
