Personal Insights

My Greatest Strengths
  • Listening first to my clients.
  • Being a dealmaker rather than a dealbreaker.
  • Strong advocacy while remaining calm and not alienating counterparties to a transaction.
  • Contributing business judgment as part of my legal advice.
  • I was the Co-Chair of my prior firm’s M&A practice group.

  • I served eight years as Managing Partner of my prior Am Law 200 firm, and I was one of just a few members to serve two terms on its Executive Committee.

  • I was recognized as one of the top attorneys in the country among an elite group of 24 Mergers & Acquisitions attorneys named to the BTI Client Service All-Star Team, a list that reflects the results of an annual survey of general counsels released by the respected BTI Consulting Group. I was one of 307 attorneys named nationwide as a BTI Client Service All-Star, and for the M&A recognition, I was the only attorney in Pennsylvania named to the list.

  • I was the two-year captain of my high school tennis team and still play singles several times each week.

  • I am a math geek and self-taught duplicate bridge player.

  • The medical gene skipped my generation – my father and uncle were medical professionals, and my son is a fourth-year medical resident at Thomas Jefferson University.

What Drives Me
  • Many of my clients have become my friends, and rely on my business and legal judgment. I joined RCCB to continue my career and thereby be able to continue serving these friends. I have been very fortunate in life and want to “give back” to my community, and have recently spearheaded a campaign that has raised $625,000 to date for organizations that support the food insecure.
