  • What previous experiences, prior to your work at Balch, influence your practice?

    The experience that most influenced my practice and provided me with the deepest exposure to and understanding of the electric utility industry was serving as Senior Counsel at what is now known as Dominion Energy Services, Inc. In that role, I  gained an in-house perspective in representing Dominion in a wide array of electric transmission matters and NERC-related issues. Also in that role, I was able to serve as the Chair of PJM Interconnection LLC’s (PJM) Transmission Owners Agreement-Administrative Committee (TOA-AC) Legal Issues Team, where I got to work with PJM transmission owners on various TOA-AC initiatives.

  • What type of clients do you represent?
    I primarily represent regulated public utility companies and their affiliates.  In addition, I have represented independent transmission and generation developers and owners, electric cooperatives, and other entities involved in the electric energy industry. 
  • What type of matters do you work on most often?
  • Which courts or agencies do you most often appear before on behalf of your clients?
