Marc Christopher Lenahan

About me



The Lenahan Law Firm - with its Principal Office in Dallas - helps the severely injured and those that lost a loved-one, all across Texas & in North Dakota. Severe injury law is all we do.


And as we represent only a select number of clients at a time, you will get the personal attention you deserve.  We suggest asking any attorney you interview this question, "How many cases and how many attorneys are in your firm?"  The differences are enormous.


Mr. Lenahan has been afforded Lifetime Membership in the Multi-Million Dollar Advocates Forum for his successes under the laws of several different states across the nation.


And though Marc has received many honors, he'll will be the first to tell you that many great attorneys have few honors, and many unimpressive ones have plenty. Honors don't mean that much to him.  Instead, he suggests, read what the attorneys' clients have said about them.  We think you'll find that Mr. Lenahan's reviews are second to none, and he takes great pride in the kind words of his clients.


Mr. Lenahan's Health Law Partner is Kathleen Kearney.  Kathleen is an excellent lawyer.  She is also a Board Certified Registered Nurse.  Her specialty?  Pediatric Nursing.  In fact, she has a Master’s Degree in it.  And she teaches Legal & Ethical Issues for R.N.s for a well-respected university’s School of Nursing.


The Firm's Appellate Law Partner is P. Wes Black.  He is Board Certified in Civil Appellate Law by the Texas Board of Legal Specialization  As lead appellate counsel in over 100 proceedings, Wes has practiced before state and federal courts at all levels, including the Texas Supreme Court and the Fifth Circuit Court of Appeals.  Prior to representing clients in court, Wes obtained valuable judicial experience working for a Court.  He served as the briefing attorney for the Chief Justice of the Tenth Court of Appeals.


The Firm's Litigation Partner is Nathan Barbera who, before joinging the Lenahan Law Firm, served as an insurance defense attorney for 15 years.


The Firm is paid on a contingency-fee, plus court costs and expenses basis; which means we only get paid if we find a way to help.


The consultation and call are always free.  Day or night, from anywhere at all, your call is always welcome: 888.473.2820 (toll-free). Our web site is: 




Marc married his school sweetheart, and they have two beautiful children.
