Where Catherine Focuses Her Practice

Probate & Trust and Estate Litigation

With more than 30 years in Tulsa County courtrooms, Catherine guides executors and families through probate from first filing to final decree, and litigates the hard cases — will contests, disputed trusts, and fiduciary claims — when an estate cannot be settled amicably. Clients also rely on her for estate planning that prevents those disputes in the first place.

Adoption

Adoption is personal for Catherine: she is an adoptive parent herself and co-built this firm on adoption law. She has walked hundreds of Tulsa families through private, stepparent, relative, and agency adoptions — from consents and terminations through the finalization hearing.

Family Law, Parenting Coordination & Guardian ad Litem

Catherine represents clients in divorce, custody, and support matters, and courts across Tulsa County appoint her as a parenting coordinator and guardian ad litem — neutral roles that require the trust of judges on both sides of the docket. Related: guardianship.

Working With Catherine

Every matter begins with a free, confidential consultation where Catherine explains your options, the realistic outcomes, and the cost in plain English. As a founding partner she sets the standard the whole firm follows: direct attorney access, careful preparation, and honest advice — even when the honest advice is not to litigate.

One Firm, Full Coverage

Because Catherine practices alongside attorneys in criminal defense, elder law, and civil litigation, her clients get seamless help when a matter crosses practice lines. Few Tulsa law firms pair this depth with 30 years of continuous local practice.
