About me

Working with individuals and families in matters related to  divorce and separation; child support; child custody; marriage and prenuptials; and more.  Visit to learn more about the services we provide.



I am an Arizona native and began my legal career with Udall Shumway PLC more than 39 years ago.  I  devote  my  practice to family law, guardianship, conservatorship and probate matters.


Family Law


I am an Arizona State Bar Certified Family Law Specialist and have practiced in this area of law for more than 39 years.  I routinely handle matters involving all aspects of child custody, paternity, relocation and interstate custody issues under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), child and spousal support issues, cases with issues of complex valuation and division of property, assets and debts.


I currently serve as a judge pro tem for the Arizona Superior Court in Maricopa County, primarily in family law cases.  As an adjunct to my responsibilities as a judge pro tem, I have served as a settlement judge for the Alternate Dispute Resolution (ADR) office of the Maricopa County Superior Court.


Guardianship and Conservatorship


I also practice in the area of guardianships and conservatorships for minors and adults. This includes initiating the proceeding, complying with annual court filings, litigation issues and termination.  Because of my experience as a probate and trial attorney, I am often asked to assist in these types of cases when litigation is required.
