Oberti Sullivan LLP: The Only Houston Employment Firm to Win a Case Before the U.S. Supreme Court

Mark Oberti argued and won a 2017 case before the U.S. Supreme Court under the federal Fair Labor Standards Act — a feat the firm’s own materials describe as unmatched by any other Houston employment law firm — and both he and named partner Ed Sullivan are Board Certified in Labor and Employment Law by the Texas Board of Legal Specialization.

At a Glance

Origin and Background

Mark Oberti and Ed Sullivan founded Oberti Sullivan LLP in 2010 after both had been partners at a nationally recognized employment law firm. Both hold Board Certification in Labor and Employment Law from the Texas Board of Legal Specialization, a credential the firm’s own materials note is held by less than 1% of Texas attorneys. The firm’s office at 712 Main Street shares its downtown Houston suite with at least one other independently branded employment boutique profiled in this directory, a common arrangement among specialized solo and small-firm practices in the building.

Practice Concentration

The firm’s stated track record spans both sides of the employment relationship — Oberti has achieved six- and seven-figure settlements and verdicts for executives and employees, while also obtaining more than 50 summary judgments on behalf of employers. Awesome Attorneys is disclosing directly that this is a mixed-representation practice, not an employee-only or employer-only firm. See this Houston Employment & Labor directory for how this compares to firms that represent only one side. The firm’s most notable case is Oberti’s 2017 win before the U.S. Supreme Court under the Fair Labor Standards Act.

Track Record

Independently verifiable results include a 2013 case in which Texas Lawyer magazine named Oberti “Litigator of the Week” after a $2.9 million jury verdict in an age discrimination case, a 2016 FLSA retaliation trial verdict, and the 2017 U.S. Supreme Court FLSA appeal win. Best Lawyers named Oberti “Lawyer of the Year” for Houston Litigation – Labor and Employment in both 2018 and 2024.

Client Voice

The firm states it has more than 140 five-star Google reviews from clients, with attributed testimonials describing attorneys who “work late nights and weekends” and “go to battle” for clients. Awesome Attorneys did not identify a pattern of negative or unresolved reviews warranting disclosure for this firm.

Beyond the Courtroom

Oberti has presented continuing legal education programming to the State Bar of Texas on “Top 15 Things New Employment Lawyers Need to Know,” alongside other Houston employment attorneys — a documented contribution to training newer lawyers in the field rather than a generic community-service claim.

Recognition for This Houston Employment & Labor Attorney

Both named partners hold Board Certification in Labor and Employment Law from the Texas Board of Legal Specialization, the credential this publication requires before using “specialist” language. Chambers USA — a peer-review ranking service distinct from marketing-program awards — ranks the firm Band 1 for Labor and Employment, Mainly Plaintiffs, and names it a Spotlight firm for Houston. U.S. News–Best Lawyers rates the firm a Regional Tier 1 Firm across three employment-law categories.

Texas Legal Backdrop

Texas follows the doctrine of at-will employment, meaning an employer can generally terminate a worker for any reason or no reason absent a legally protected exception such as discrimination or retaliation. The firm’s Supreme Court win specifically involved the federal Fair Labor Standards Act, which governs minimum wage and overtime pay and operates independently of Texas state wage law. None of this is legal advice; a specific employment matter should be evaluated by a licensed attorney based on the actual facts involved.

Awesome Attorneys Assessment

Oberti Sullivan’s clearest, most checkable differentiator is a U.S. Supreme Court win under the FLSA — a genuinely rare credential among Houston employment boutiques — backed by Chambers USA’s Band 1 peer ranking and dual TBLS certification. The honest trade-off: this is a mixed-representation firm that has obtained summary judgments for employers as well as verdicts for employees, so a prospective client should confirm directly which side the firm would represent them on for their specific dispute rather than assuming a one-sided advocate. For a complex, high-stakes employment matter where appellate-level litigation experience matters, this firm’s track record is a genuine, checkable differentiator.
