Alex P. Rosenthal · Florida Commercial Mediator and Arbitrator · Statewide
Private mediation and arbitration for commercial disputes throughout Florida. Drawing on thirty-seven years of active trial and appellate practice, applied to the same disputes now handled as a neutral.
“The best mediator in the room is the one who has actually tried the case the parties think they want to try.” — Practice Philosophy
Alex P. Rosenthal has spent thirty-seven years as a statewide Florida commercial litigator, with active trial and appellate matters in courts throughout the state, including Broward, Miami-Dade, Palm Beach, Monroe, Collier, Hillsborough, and Orange counties. His appellate practice includes appearances in all six Florida District Courts of Appeal, the Florida Supreme Court, and the Eleventh Circuit Court of Appeals, with reported decisions including matters of first impression in Florida and the Eleventh Circuit. He is admitted to The Florida Bar, the District of Columbia Bar, and the bar of the Supreme Court of the United States. That statewide trial-floor and appellate experience is the substantive foundation that informs his work as a Florida Supreme Court Certified Circuit Civil Mediator and Florida Certified Arbitrator. Mediations are conducted primarily by Zoom, with in-person sessions available throughout the state when the parties or the matter warrant the convening.
Judges in the Seventeenth Judicial Circuit regularly appoint this practice as mediator in their commercial dockets, with appointments arriving on a weekly basis.
The mediator selection conversation is, at bottom, a question of credibility with both sides. Counsel who recommend a neutral are placing professional capital behind the recommendation. The objective here is to be a name that carries weight precisely because the underlying litigation experience is real, current, and acknowledged on both sides of the bar.
Mediations are conducted primarily by Zoom, which has become the practical default for commercial mediation across Florida and accommodates parties, counsel, and clients located outside the immediate region without the logistical burden of travel. In-person sessions are readily available where the parties or the dispute warrant the convening, at the firm's Weston office, at the Brickell City Tower Miami office by appointment, or at counsel's offices when more convenient for the parties. Arbitration engagements are accepted as sole arbitrator and as panel member in matters governed by AAA Commercial Arbitration Rules, JAMS rules, or Florida statutory arbitration procedures.
Contract disputes, commercial fraud, business dissolution, guaranty enforcement, and adjacent commercial matters. Substantive Florida commercial law experience applied to the neutral role in the full range of business disputes.
Tortious interference with contract and prospective business relationships, misappropriation of trade secrets under the Florida Uniform Trade Secrets Act, unfair competition, breach of fiduciary duty, and civil conspiracy claims that overlay the substantive torts.
Shareholder oppression under Chapter 607, LLC governance under the Revised Uniform Limited Liability Company Act, partnership dissolution, buyout proceedings, and derivative claims. Personal and business-continuity dynamics require particular sensitivity.
Contract disputes across the construction chain, delay and disruption claims, defective work, mechanic's lien enforcement and defense under Chapter 713, bond claims, and the multi-party proceedings that construction disputes typically produce.
Wrongful termination, discrimination, retaliation, wage and hour matters, non-compete enforcement under Section 542.335, executive compensation, and severance and separation disputes. Both statutory framework and human dynamics require attention.
Commercial leasing under Chapter 83 Part I, real property transactional disputes, title matters, easement and boundary disputes, restrictive covenant matters, and mortgage-related litigation. Commercial landlord-tenant matters have distinctive settlement dynamics.
The least productive mediations are the ones in which the neutral functions as a courier, carrying dollar figures from one room to another until the bracket narrows or the parties run out of time. Counsel who bring serious commercial matters warrant more than that. Four working commitments define what counsel can expect from an engagement of this practice, whether the matter is heading to trial or being worked toward resolution before it gets there.
Mediation submissions are read in full, in advance. Confidential ex parte communication is welcomed. The expectation is that the mediator arrives knowing the docket as well as the parties do, and that the substantive law governing the dispute is understood before the parties sit down rather than learned in the hallway.
Mediators are not permitted to render legal opinions or predict outcomes, and they should not. What an experienced commercial litigator can do is share the candid lessons of thirty-seven years in courtrooms across Florida, in plain terms, in caucus. Parties are challenged to weigh the genuine costs, risks, and unknowns that real litigation produces, rather than hypothetical concerns drawn from a textbook. That is a different exercise from telling a party it will lose. It is the exercise of helping counsel and client see the dispute with the clarity that distance and experience provide.
Almost every commercial dispute involves concerns the complaint does not articulate. Reputation, ongoing business relationships, family dynamics in closely held entities, the cost of continued distraction, the value of finality, the principle of the matter. Counsel who have lived these cases know how often the apparent dispute over dollars is in fact a dispute about something else. Caucus time is used to surface those interests, with appropriate sensitivity, so that the resolution offered is responsive to what is actually at stake rather than to a partial articulation of it.
Mediations that look stuck at four o'clock are often the ones that settle at six. The default posture is to keep the parties working when there is meaningful work still being done. When there is not, impasse is called honestly rather than dragged through additional hours that benefit no one. Counsel and clients should leave knowing whether the matter was given a real chance, and if not settled, why.
Substantive analysis of the disputes, the process, the procedural framework, and the strategic decisions counsel and parties face. Written by an active litigator with thirty-seven years of Florida trial and appellate practice, applied to the same disputes now handled as a mediator and arbitrator.
The substantive work that supports mediation and arbitration practice is ongoing rather than retrospective. Active matters in the firm's commercial litigation practice include insurance coverage disputes, commercial lease enforcement, construction and construction defect litigation, partnership and shareholder disputes, trade secret protection, post-judgment collection, employment and non-compete enforcement, and real estate litigation. The disputes that arrive at mediation are, in substantive terms, the same disputes that arrive at trial. The perspective offered as a neutral is informed accordingly.
Reported decisions over thirty-seven years of practice include several rulings of first impression and precedent-setting opinions in Florida and the Eleventh Circuit. In United States v. Stein, 881 F.3d 853 (11th Cir. 2018) (en banc), the Eleventh Circuit overruled more than thirty years of contrary precedent and held that an otherwise admissible affidavit is sufficient to defeat summary judgment even though self-serving and uncorroborated. In Martin v. Florida Power and Light Co., 909 So.2d 555 (Fla. 4th DCA 2005), the Fourth District established the duty of utilities in underground damage cases, the first Florida decision to do so. In Briceno v. Sprint Spectrum, L.P., 911 So.2d 176 (Fla. 3d DCA 2005), the Third District addressed the ability to bind parties to standard contractual terms posted on the internet. In J & P Transp., Inc. v. Fidelity and Casualty Co. of New York, 750 So.2d 752 (Fla. 5th DCA 2000), the Fifth District established automatic trebled civil damages following a criminal conviction for theft, the first Florida decision on the question. In Enriquillo Export & Import, Inc. v. M.B.R. Industries, Inc., 733 So.2d 1124 (Fla. 4th DCA 1999), the Fourth District clarified that payment by check does not constitute payment when mailed.
Recent appellate work has included GFA International, Inc. v. Trillas, 327 So.3d 872 (Fla. 3d DCA 2021), in which the Third District reversed the denial of a temporary injunction enforcing a non-compete agreement and rejected arguments that the trial court had improperly weighed individualized economic hardship in violation of Section 542.335; Liberty Mutual Insurance Co. v. Wolfson, 299 So.3d 28 (Fla. 4th DCA 2020), affirming a $1.6 million underinsured-motorist verdict and addressing setoff calculations; Off the Wall & Gameroom LLC v. Gabbai, 301 So.3d 281 (Fla. 4th DCA 2020), a case of first impression holding that children who procure a contract by fraud are bound by the contract and cannot invoke the infancy defense; Fields v. Toussie, 295 So.3d 1191 (Fla. 4th DCA 2020), affirming the issuance of a writ of bodily attachment against a judgment debtor on a domesticated foreign judgment exceeding $8 million; Inside the Art of Craftmanship Corp. v. Design Center of the Americas, 237 So.3d 378 (Fla. 4th DCA 2018), addressing rent-deposit requirements in commercial-tenant litigation; and Acquisition Trust Company, LLC v. Laurel Pinebrook, LLC, 226 So.3d 325 (Fla. 2d DCA 2017), reversing a dismissal with prejudice in a right-of-first-refusal dispute.
Trial-court work has included substantial recent results, among them Venture Investment Group II, LLC v. Nurish.me, Inc., in the Eleventh Judicial Circuit in and for Miami-Dade County, in which the firm obtained summary judgment in the amount of $7,889,660.79 on claims for breach of two promissory notes, and Jacob Taylor and Studygate, LLLC v. Studygate, Inc., 2025 WL 1658205 (S.D. Fla. June 3, 2025), in which the United States District Court for the Southern District of Florida dismissed all claims against nonresident defendants for lack of personal jurisdiction in a complex case involving a $675,000 asset purchase agreement.
Federal-court precedent over the years has included Design Center of the Americas, LLC v. Mike Bell, Inc., 254 F.Supp.3d 1339 (S.D. Fla. 2014), the first published opinion in the Southern District of Florida clarifying that a counterclaim is irrelevant to the amount-in-controversy analysis in a removal setting; Almany Investors, Ltd. v. Nextel South Corp., 2015 WL 74091 (S.D. Fla. 2015), confirming termination rights under a Communications Site Lease Agreement following the iDEN network shutdown; Harty v. SRA/Palm Trails Plaza, LLC, 755 F.Supp.2d 1215 (S.D. Fla. 2010), addressing standing limitations under the ADA; Watson v. Adecco Employment Services, Inc., 252 F.Supp.2d 1347 (M.D. Fla. 2003), one of the first decisions to address limitations on temporary-staffing-firm liability for discrimination against a temporary employee; and In re Turner, 519 B.R. 354 (Bankr. S.D. Fla. 2014), awarding Rule 11 sanctions in a Chapter 13 bankruptcy proceeding.
Mr. Rosenthal serves as an independent neutral on the panel of National Arbitration and Mediation, a leading alternative dispute resolution provider in the United States. NAM panel membership reflects independent vetting by an institutional ADR provider and gives counsel the assurance that comes from a neutral evaluated and selected against national standards. Engagements through NAM are accepted alongside party-selected and court-appointed work. Ongoing service as a court-appointed mediator and arbitrator continues to refine the practice. Recent arbitration work has included service as sole arbitrator in commercial disputes, with written final opinions issued in matters governed by institutional arbitration rules.
Recognition over the years has included Best Lawyers in America in both Commercial Litigation and Construction Litigation; selection to the Florida Super Lawyers list; AV Preeminent rating from Martindale-Hubbell; selection to Florida Trend's Legal Elite; election as Senior Fellow of the Litigation Counsel of America; and inclusion in U.S. News and World Report's Best Law Firms. Of these, the peer-reviewed and editorial honors are noted because they reflect evaluation by the legal community itself rather than by paid-listing services. The point of cataloguing the work is not promotional. It is the verifiable record on which counsel may evaluate whether the substantive depth offered is genuinely commensurate with the complexity of the dispute presented.
