Andrew Gendron


Andy Gendron is a general civil trial lawyer who has tried over 70 cases to verdict and finds creative business solutions for his clients.

He regularly appears across the country in mass consolidations and class actions involving complex expert issues in areas such as:

  • product-liability cases;
  • toxic torts;
  • environmental suits;
  • shareholder class actions;
  • fiduciary matters;
  • corporate-governance disputes; and
  • legal malpractice defense.

He has successfully resolved many environmental and toxic-tort class actions, whether through the defeat of certification attempts, decertification efforts, or persuading plaintiffs to withdraw class pleadings.

Representative Clients

Andy's clients include a major pharmaceutical manufacturer, a commercial bank holding company, a major petrochemical manufacturer, several large chemical and consumer-product manufacturers, real estate investment trusts, and high-net-worth individuals.

Significant Matters

  • He obtained dismissal of securities-fraud claims on behalf of an early-stage biotechnology company, and then settled the remaining, potentially crippling claims on terms that allowed the client to recapitalize and thrive.
  • He obtained dismissal of a six-count legal-malpractice complaint under the doctrine of forum non conveniens, and then filed suit for outstanding receivables against the same plaintiff in a more convenient forum. When the former plaintiff then filed its claims as a six-count counterclaim, Andy obtained dismissal of all claims with prejudice, forced the opponent to court-ordered mediation, and obtained a favorable recovery for his client.
  • Andy also helped a petroleum refiner and marketer defend against environmental lawsuits related to two Maryland sites, which alleged property damage and personal injury on behalf of more than 1100 plaintiffs. Based on the strategic plan he developed under Maryland law, the litigation ended as a victory for the client after trial and appeals.
  • Andy frequently represents clients in disputes related to governance of publicly and privately held real estate investment trusts, corporations, and partnerships.
  • Andy has served on the national counsel team for a manufacturer of prescription pharmaceuticals, and as trial and liaison counsel in tobacco litigation pending in Maryland.
  • He represented a wholesale food distributor and its corporate parent in litigation involving breach-of-contract and wrongful-termination claims by the distributor’s former chief executive, as well as his clients’ counterclaims for the executive’s breaches of contract and fiduciary duties.
  • Andy twice successfully defended pigment and paint manufacturers before the trial and appellate courts of Maryland.
  • In a case of first impression, he won a seven-year battle over alleged housing discrimination, with an appellate mandate ordering dismissal of the charges.


Through Esperanza Center, Andy represents minors and their families in Special Immigrant Juvenile Status proceedings.

Andy recently served as a member of the Board of Trustees of Saint Mary’s Seminary & University and as a member of its Finance and Education and Formation Committees. He was co-chair of the 19th and 20th Lawyers' Campaigns for CollegeBound Foundation, a nonprofit program that helps Baltimore City public school students achieve a post-secondary education.

He is also a past chair of the Mission & Planning and Executive Committees and a past member of the Finance Committee of the Catholic Community of Saint Francis Xavier, where he is also a lay youth minister and lector. He has served on the boards of other charitable and community organizations, such as the Homeless Persons Representation Project. He has been a volunteer for Our Daily Bread and Christopher Place.

For several years, he was a faculty member of the Maryland Institute for the Continuing Professional Education of Lawyers and the Maryland Institute for Trial Advocacy.
