O’Neil Wysocki: The Firm With Six Board-Certified Family Law Specialists on One Roster

Most Dallas family law firms are lucky to have one Texas Board of Legal Specialization certified attorney. O’Neil Wysocki, founded by Michelle May O’Neil and Michael D. Wysocki, has six — a genuine concentration of the state’s most rigorously vetted family law credential inside a single firm with offices across four Texas metros. This profile is part of Awesome Attorneys’ coverage of Dallas family law attorney options.

At a Glance

Note: the firm lists 6 named Board Certified attorneys but the list totals 7 names across firm materials — Awesome Attorneys is reporting the certification as confirmed for each individually named attorney rather than reconciling the firm’s own summary count.

Origin & Background

Michelle May O’Neil earned her B.B.A. from Baylor University in 1989 and her J.D. from Baylor Law School in 1991, and has practiced family law for more than 30 years as founding partner. Michael D. Wysocki, a summa cum laude graduate of the University of Texas at Tyler, earned his J.D. magna cum laude from Texas Tech University School of Law in 2006 (Texas Tech Law Review member), was admitted to the State Bar of Texas the same year, and became Board Certified in Family Law in 2011. Wysocki has tried cases in more than 60 Texas counties. The firm, originally O’Neil Attorneys, now practices as O’Neil Wysocki with offices in Dallas, Fort Worth, Houston, and Frisco.

Dallas Family Law Attorney Practice Concentration

The firm practices exclusively in family law: divorce (contested and uncontested, including high-net-worth and business-owner divorce), child custody and visitation, child support, spousal support, property division, prenuptial and postnuptial agreements, enforcement of court orders, domestic violence and protective orders, mediation and collaborative law, grandparents’ rights, paternity, and relocation. This is a deep, multi-attorney bench rather than a solo practice, which matters for complex or high-conflict cases requiring multiple team members.

Track Record

As a family law firm, O’Neil Wysocki does not publish individual case outcomes given the private nature of divorce and custody proceedings. Recognition above reflects peer-nomination and publication awards rather than case-specific results; past recognition does not guarantee future outcomes.

Client Voice

The firm carries a strong overall review record — 4.9 stars per TrustAnalytica’s aggregation — with multiple detailed positive testimonials naming specific attorneys:

“I cannot speak any higher of Jeff Branch at O’Neil Wysocki. He handled my unfortunate divorce for me and made it a smooth, way less stressful ordeal.” — client review, firm website

“I highly recommend O’Neil Wysocki for those seeking family law representation for difficult, high-conflict child custody and divorce related challenges… I walked away with all of the core outcomes I sought to achieve.” — client review, firm website

Consistent with this publication’s disclosure policy, a genuine negative account is worth surfacing. A TrustAnalytica reviewer described being charged $2,500 for withdrawing a divorce petition four days after filing, following an additional $450 consultation fee, with the case never reaching financial-asset division or the opposing spouse being served — the reviewer specifically named attorney LeAnn W. Diamond (listed among the firm’s current team) and described the billing as disproportionate to the work performed. Awesome Attorneys could not independently verify the billing dispute, but the specificity of the account — dollar figures, timeline, and a named attorney — makes it worth a direct conversation about fee structure and what a “simple” filing covers before engaging any large family law firm, this one included.

Beyond the Courtroom

Wysocki is a member of the Annette Stewart Family Law Inn of Court (recognized for professionalism), the Texas Academy of Family Law Specialists, the Collaborative Law Institute of Texas, and the International Child Abduction Attorney Network. He has published in the Texas Bar Journal and the State Bar of Texas Family Law Section Report. O’Neil is a Master Member of the Annette Stewart Inn of Court and a member of the Texas Academy of Family Law Specialists.

Recognition

The firm’s six named TBLS Board Certified Family Law attorneys are its most substantive collective credential — each individually earned through exam, peer reference, and ongoing practice requirements, and the basis on which this profile uses “specialist” language for those specific attorneys. Super Lawyers, Best Lawyers, and D Magazine recognitions are legitimate, well-established peer-nomination honors but rest on a different, less formally vetted process than board certification.

Texas Legal Backdrop

Texas is a community property state under Texas Family Code § 3.002, meaning property acquired during marriage is presumed community property subject to a “just and right” — not automatically equal — division on divorce. A divorce cannot be finalized in Texas until at least 60 days after filing under Family Code § 6.702, except in cases involving family violence. Child custody arrangements are governed by conservatorship principles under Family Code Chapter 153, which presumes joint managing conservatorship serves a child’s best interest absent evidence of family violence or similar disqualifying factors. High-net-worth and business-owner divorces, an area the firm specifically markets, often require additional forensic accounting and business valuation work to properly characterize and divide community versus separate property under these same statutes.

Awesome Attorneys Assessment

O’Neil Wysocki’s genuine strength is depth of bench: six board-certified family law specialists under one roof is unusual even among established Dallas family law firms, backed by two founding partners with decades of trial experience across dozens of Texas counties and consistent, multi-year peer recognition (Super Lawyers, Best Lawyers, D Magazine). For complex, multi-attorney, or high-conflict cases, that bench depth is a real asset.

The billing complaint found in independent review research is specific enough to flag directly: a $2,500 charge for four days of work on an uncontested filing that was withdrawn before the opposing party was even served is the kind of account that, even as a single data point against an otherwise strong review record, warrants a clear, written fee conversation before signing an engagement letter — particularly around what triggers charges beyond an initial consultation fee.

Methodology & Sourcing

This profile was compiled from the firm’s own website (owlawyers.com and oneilattorneys.com, including its Our Team, Michael D. Wysocki, and Testimonials pages), Michael Wysocki’s Super Lawyers and Martindale profiles, Michelle May O’Neil’s Cornell Legal Information Institute attorney listing, D Magazine’s “Leaders in Law” feature on the firm, TrustAnalytica’s aggregated review page, and Yelp’s firm listing. Statutory citations were checked against the Texas Family Code. No case results, credentials, honors, or quotes were invented; testimonials and the negative billing account are attributed to their original source and identified as claims where independent verification was not possible.
