Attorney Information

Overview

For 30 years, Mark has been in private practice with a focus on executive compensation, employee benefits (especially ESOPs), and retirement plan fiduciary matters, not only from a tax and labor perspective, but also from a business, governance, tax, securities, and litigation perspective. He currently serves as immediate Past President of the prestigious American College of Employee Benefits Counsel after previous terms as its Treasurer, Vice-President, and President. Mark is Chambers-rated, and works regularly with the American Benefits Council (where he was an executive board member for many years).

Mark's clients include public and private companies; he also has significant experience with not-for-profit organizations from both a governance and a executive compensation perspective. His business oriented pay-for-performance approach has led to his role as special counsel to compensation committees, as well as to his spearheading of projects designed to link executive compensation to corporate goals and to the enforcement of post-employment covenants relating to trade secrets and restrictive covenants (such as non-competition agreements).

Mark also teaches at Georgetown Law School. His courses have focused on executive compensation and governance, the design of benefit plans and employment-related agreements, and employee stock ownership plans (ESOPs). Associated with those courses is his substantively rich website found at www.executiveloyalty.org and www.graymatternetwork.org .

Prior to joining The Wagner Law Group, Mark served for almost 20 years as co-chair of the employee benefits (ERISA) practice as was a partner at a prominent international Washington, D.C. law firm of nearly 1,000 attorneys.

How do I choose a lawyer?

Consider the following:

  • Comfort Level – Are you comfortable telling the lawyer personal information? Does the lawyer seem interested in solving your problem?
  • Credentials – How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?
  • Cost – How are the lawyer's fees structured — hourly or flat fee? Can the lawyer estimate the cost of your case?
  • City – Is the lawyer's office conveniently located?

Not sure what questions to ask a lawyer?

Here are a few to get you started:

  • How long have you been in practice?
  • How many cases like mine have you handled?
  • How often do you settle cases out of court?
  • What are your fees and costs?
  • What are the next steps?

Want to check lawyer discipline?

It is always a good idea to research your lawyer prior to hiring. Every state has a disciplinary organization that monitors attorneys, their licenses, and consumer complaints. By researching lawyer discipline you can:

  • Ensure the attorney is currently licensed to practice in your state
  • Gain an understanding of his or her historical disciplinary record, if any.
  • Determine the seriousness of complaints/issues which could range from late bar fees to more serious issues requiring disciplinary action.
