Sean’s years of experience both as an active duty US Army Captain and 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. He 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 Texas Trial Lawyers Association, The State Bar of Texas International Law Section, The Houston Trial lawyers Association and the State Bar of Texas Military and Veterans Law Section. Sean is a current member of the Houston Bar Association and is licensed to practice law in both New York and every State and Federal Court in Texas. Before relocating temporarily to New York, Sean also served in Texas as a military law adviser to a number of family law attorneys. Sean previously served at Fort Hood as an Army Captain, where he was the primary legal adviser to the President (O-6) of the Fort Hood Officer Separation Board after having started his Army career in 1998 as a private (E-1) Field Artilleryman and ascending to the rank of Captain (O-3). 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. Sean has been involved in all stages of insurance pre-trial and trial litigation including mediations, depositions, and fierce discovery disputes. Today, he uses his sage wisdom gained from these fierce battles across Texas and the country to benefit his clients”

Prior to becoming an attorney, Sean deployed as a combat arms Artilleryman to Bosnia in 1999 as a member of Operation Joint Forge. He deployed again to the Middle East after the Sept. 11 attacks as part of Task Force Blackjack in the most forward deployed US Army heavy brigade combat team during Operation Enduring Freedom in the fall of 2001 and spring of 2002. His task force would serve in both Kuwait and Afghanistan. Sean has been awarded the NATO Medal, the National Defense Service Medal, Army Service Ribbon, the Global War on Terrorism Service Medal, five Army Achievement Medals, the Good Conduct Medal and an Army Commendation Medal.

Sean holds a Master of Laws in International Law from the University of Houston Law Center. He graduated cum laude from South Texas College of Law, Houston and graduated summa cum laude from the University of Texas at San Antonio. Sean was also elected as a council member to the State Bar of Texas Military and Veterans Law Section for the 2017-2019 term.

Representative Matters

  • Robert Martinez v. State Farm Lloyds, et al., No. 16-0040, N.D. Texas; 2016 U.S. Dist. LEXIS 111334
  • An E-7 in the United States Army was charged with three counts of Article 128 (aggravated assault) and two counts of Article 92 (violation of a lawful general order). Thanks to Sean’s aggressive defense during the court-martial, his client was fully acquitted.
  • An ROTC Cadet faced disenrollment and forced recoupment of $86,000. Thanks to Sean’s hard work and aggressive defense, he was able to get the college’s US Army ROTC Disenrollment Board to recommend active military service and no recoupment, which saved the cadet $86,000 and moved him forward into his desired goal.
  • An Air Force Chaplain was removed from duty at a base in Europe for creating a “hostile work environment” by using excessive profanity on repeated occasions and calling subordinates unflattering names. Through Sean’s aggressive advocacy, the Air Force Chief of Chaplains removed the Chaplain’s Letter of Admonishment and Unfavorable Information File.
  • A client was facing arbitrary and capricious action from a consulting company as a result of prohibited disability discrimination. Sean’s aggressive advocacy helped his client leave the company in May 2016, receive salary through the end of the year and settle with the company for six months of compensation, totaling approximately $30,000.
  • A Senior E-7 non-commissioned officer was facing a relief for cause evaluation. Sean’s tireless commitment and aggressive advocacy helped convince the chain of command to write a “change of rater” NCOER, which will not slander the officer’s future military career.
  • A client was facing $82,000 in indebtedness collections from the Defense Finance and Accounting Services (DFAS). Negotiating with the Office of the General Counsel, Sean aggressively advocated for a suspension in collections by DFAS, pending adjudication of his client’s Combat Related Special Compensation (CRSC) application. The Office of the Special Counsel also agreed to audit the claim of indebtedness.
  • A former ROTC Cadet was stuck in limbo for four years after he was found medically unfit for service by the Washington National Guard. Through Sean’s aggressive advocacy, he was able to obtain an honorable discharge for his client through the Assistant Secretary of the Army Manpower & Reserve Affairs, no ROTC recoupment and no further service obligation.
  • An Army Reserve Chaplain was demoted by his employer after he was abruptly mobilized. Sean aggressively negotiated with the Office of the General Counsel and obtained a restoration of his client’s former position, as well as appropriate back pay and future differential pay compensation.
  • An Army private was facing an involuntary separation action for failing to disclose a tumor in his leg to his recruiter. Through Sean’s tireless and aggressive advocacy, his client received a medical discharge, instead.
  • A National Guardsman went to Afghanistan without permission and was declared AWOL by his unit. With his client facing a negative discharge, Sean aggressively worked to gain an honorable discharge for the guardsman.
  • An ROTC Cadet was facing the prospect of paying $80,000 in recoupment after he was dis-enrolled in the program due to a low GPA score. Sean filed a rebuttal, arguing that his client’s low score was due to administrative error, and that his APFT failure was not included in the dis-enrollment notification. Thanks to Sean’s aggressive defense, he got the ROTC board’s decision vacated, and the Cadet was able to appeal his dis-enrollment to a new review board.
  • An ROTC Cadet faced a board dis-enrollment after self-admitting to drug use, along with alleged deficient performance and military bearing issues. Thanks to Sean’s aggressive defense, the initial disenrollment board was determined to be invalid, and the Commander withdrew the proceedings.
  • A client felt that his military career was being ruined by his command because OERs were not being processed, he was receiving letters of reprimand and a Statement of Reasons was initiated. Compounding his case was the fact that he was having an extra-marital affair with a foreign national. The client simply wanted to reach retirement from service with his security clearance intact. Sean worked quickly and proactively to anticipate and react to the changing dynamics of his client’s case.
  • An Air Force ROTC Cadet was charged with DUI in Iceland and faced disciplinary action from his command back at school in the United States. Sean aggressively defended his client by arguing the testing procedures in Iceland were unreliable, and the blood draw and forced nature of it were unconstitutional, not worthy of reciprocal acknowledgement. The investigating officer and the PMS agreed to drop the charges, but Command disagreed and disenrolled the client. Sean then filed an appeal to a higher command, which reinstated the cadet.
  • A client was facing a security clearance matter involving foreign influence and foreign preference. The client owned property in Thailand, was married to a Thai national with no U.S. citizenship or residency, had several Thai bank accounts, properties and businesses, and had been audited by the IRS for not paying appropriate taxes for income earned in Iraq while having a home of record in Thailand. Thanks to Sean’s aggressive defense, he was able to get his client’s security clearance case resolved at the Department of Defense Consolidated Adjudications Facility, rather than the Defense Office of Hearings and Appeals level.
  • A client was facing collection for $20,000 in debt to the Department of Veterans Affairs (VA) while her husband was an Active Guard Reserve in Albany. Sean reached out to U.S. Senator Kirsten Gillibrand’s office, which got the VA to drop its claim of indebtedness against his client.
