Sean C. Timmons

Sean’s years of experience as an active-duty US Army Captain in the selective and prestigious US Army Judge Advocate General’s (JAG) Corps are a valuable asset to Tully Rinckey PLLC’s military law practice group. Having served his country honorably at the largest military installation in the world in Fort Hood, Texas as a Judge Advocate from 2009 until 2013, Sean is an aggressive and tenacious advocate for all service members facing legal issues. He is able to pull from his significant and diverse experience as an active-duty attorney in the Army JAG Corps, and as a civilian military law attorney, he forcefully and efficiently represents service members in both administrative and criminal proceedings. Sean originally joined Tully Rinckey’s Albany, N.Y., office as a Senior Associate, where he was first promoted to Partner and eventually Managing Partner of the firm’s first footprint in the state of Texas.

As Managing Partner of Tully Rinckey PLLC’s Houston office, Sean oversees all of the office’s operations while concentrating his practice on military law; routinely handling cases involving Article 15s, letters of reprimand, courts-martial and officer/enlisted separation proceedings. Sean also handles federal labor and employment law cases and security clearance representation.

Sean also is a member of the Houston office’s Insurance Law Practice, where he assists clients with bad-faith litigation cases, first- and third-party coverage disputes involving CGL, business auto, commercial and residential property, and ERISA policies.

Sean is an experienced insurance coverage litigator. He has handled numerous lawsuits involving property damage claims under residential and commercial policies. He has appeared in numerous federal and state courts throughout Texas. Mr. Timmons is well-versed in coverage litigation including discovery and its limits, taking and defending depositions, motion practice, evidentiary hearings, alternative dispute resolution, and pre-trial and trial of coverage disputes.

Additionally, Sean is passionate about International Law and frequently travels the globe for the firm on behalf of his clients in each branch of service with the United States Armed Forces.

Prior to joining Tully Rinckey PLLC, Sean worked in private practice in Houston, where he was an active member of the State Bar of Texas International Law Section, and the State Bar of Texas Military and Veterans Law Section and the State Bar of Texas Insurance Law Section.

As a Judge Advocate, Sean led the effort in 2010 as Acting Chief of Fort Hood Client Services to have the Commanding General of III Corps blacklist a notoriously corrupt landlord-tenant company that was infamous for ripping off active duty soldiers.

In addition to his significant military law career Sean has tried civil cases to verdict and has extensive motion practice experience throughout the state. He has gained a vast amount of knowledge handling institutional discovery concerning insurance companies in various Hurricane and Hail Storm Multi-District Litigation in Texas.
