About Kate

Kate Beurmann-O’Neill leads our Divorce and Family Law practice. She joined Vanderpool, Frostick & Nishanian in August 2025, after accruing over two decades of legal experience.

Kate’s legal journey began in the world of Trusts and Estates,  and then turned to Health Care Law.  At entities such as Convergent AHC, Advent Health Partners, and Specialized Healthcare Partners, Kate assisted hospitals, health care systems, and patients to obtain coverage and reimbursements for complex medical claims.  Kate was involved in contractual disputes between insurers and healthcare providers, and she worked with employers and patients in order to expand some plans’ coverage for experimental and investigational treatments.

In 2020, after going through her own divorce, Kate pivoted to Family Law.  She understands the needs of her clients and their children as they navigate through this very stressful time. 

Kate’s practice encompasses the areas of Divorce, Equitable Distribution, Custody, Visitation, Child Support, Spousal Support, Marital Settlement Agreements, Prenuptial Agreements, Uncontested Adoption, Contested Adoptions and Terminations of Parental Rights, Paternity Matters, Modifications of Prior Custody, Visitation, and Support matters, and Guardianships and Conservatorships for incapacitated adults.

Kate has helped many clients through complex issues, including step-parent adoption, division of family business in a divorce, imputation of income in support matters, and issues of child custody, which involve allegations of abuse and neglect.

Additionally, Kate is trained in mediation and can assist couples who would like to work through divorce, custody, visitation, and support matters without contentious litigation.

Kate is heavily involved in the legal community, both locally and throughout the Commonwealth of Virginia.  She serves as the Chair of the Family Law Section of the Virginia Trial Lawyers Association (March 2026 – March 2027), and will soon lead the Virginia Women Attorneys Association as its President (July 2026 – June 2027).

Kate lives in Prince William County with her husband and most of their combined five children, but she practices throughout the state, including Fairfax County, Fauquier County, Loudoun County, Culpeper County, Frederick County, the City of Winchester, Rockingham County, and Warren County.

Testimonials

“Working with Kate Beurmann-O’Neill and team was an incredible experience. She guided me through one of the most difficult and emotional times of my life with professionalism, compassion, and unwavering dedication. From the very beginning, Kate took the time to understand every detail of my case and always made me feel heard and supported.

Her preparation for trial was outstanding, she was strategic, organized, and completely on top of every fact and document. During court, she was calm but powerful, articulating my position with confidence and clarity. The outcome was better than I could have hoped for, and it’s because of her expertise and hard work.

Beyond her legal skill, Kate genuinely cared about me and my daughter’s well-being. She was patient when things got stressful and always explained the process in a way I could understand. I can’t recommend her enough to anyone going through a family law matter, she’s not only an exceptional attorney but also a kind and steady advocate when you need one most.”
