About the Gray Matter Network


Founded to assist age 50+ Executives

This website arises because so many people feel unwanted in the workplace after age 50.  The stakes are especially high for executives - both in terms of their financial risks and the risk of having their talents go to waste.  For those in that predicament, we hope to help through our experience and encouragement.

The inspiration for this website comes from Mark Poerio, who is senior counsel in the DC office of the Wagner Law Group,  Throughout his 30+ years of private practice (most with Wall Street law firms), Mark has  worked almost exclusively with business executives, with his focus being on executive compensation and ERISA fiduciary matters, especially from a business, governance, tax, labor, finance, securities, and litigation perspective.  Here is Mark's email address: mark.poerio@graymatternetwork.org.

Mark is Chambers-ranked, recognized by SuperLawyers, and for over 10 years has taught executive compensation classes at Georgetown Law.  Mark recently completed his terms as President of the American College of Employee Benefits Counsel (ACEBC), and as an executive board member of the American Benefits Council. 

In addition to representing companies, executives (individually) and compensation committees, Mark also has extensive experience with changes in corporate control, employee stock ownership plans (aka ESOPs), and tax exempt organizations. For the latter, his practice ranges from general governance to executive compensation -- e.g. Code section 457(f) and 4958 tax planning and correction.
