About me

I am a partner at Hanis Irvine Prothero, PLLC. I assist people with estate planning, probate, real estate, and business transactions and litigation. This includes matters related to estate disputes, guardianships, collections, boundary disputes, construction claims, and related issues.


Due to my litigation/arbitration/mediation experience, I am called upon to assist clients in a variety of matters. I am result oriented and find great pleasure when clients reach their legal goals quickly and efficiently. When a fair resolution cannot be achieved, I fight for my clients to achieve the most beneficial result possible.  I have extensive experience in Superior and Federal courts, including trials, mediations, and arbitrations.
