A Veteran Insurance Defense Attorney is on Your Side

PictureExperience when it matters most
My name is Mark D. Willmarth, and I have been providing legal advice and representation to insurance companies and self-insured corporations throughout Southeast Michigan for more than 35 years. I have extensive experience handling insurance claims, insurance coverage issues and subrogation for our clients at every level of state and federal court. I am dedicated to providing the personal attention and respect that your company deserves.



St. Clair Shores insurance defense attorney
I provide insurance companies with a wide variety of legal services, including:

  • Tort litigation of all varieties
  • Claim management and apportionment services
  • Insurance coverage opinion letters
  • Declaratory judgments
  • Reinsurance advice and disputes
  • Bad-faith litigation
  • Professional liability litigation
  • Coverage opinion letters
  • Insurance appellate litigation
  • Arbitration and mediation

I help insurance companies resolve problems involving insurance policy coverage. I analyze each and every provision to determine the extent of coverage that is warranted under the policy, and I prepare detailed opinion letters on those findings. After providing my client with the opinion letter, I seek to resolve the issues by filing a declaratory judgment action in court. However, in certain cases, litigation may become necessary to settle issues in dispute. If that occurs, you can rest assured that I have the knowledge, skills, and drive to get you the best possible results.

I also help insurance companies in situations involving third parties. I often initiate subrogation claims against at-fault third parties to get reimbursement for any payments to insureds under their own policies.

Effective solutions with your best interests in mind
Although I have forged my reputation through my litigation abilities, I commit my best efforts wherever possible to resolving your problems without resorting to court. I understand that litigation can become expensive, and that litigation may not be the best option in your case. For these reasons, I routinely use arbitration and mediation to settle disputes for clients at much-reduced cost, and I propose settlements that have your company’s best interests in mind.
