Kathie Opel was great. She walked my wife and I through each document of our Estate Plan, answering any questions we had and talking us through scenarios we hadn't considered. We are extremely happy with their services and highly recommend them!

Kathie did a great job talking/walking us through a new Family Estate Plan. The staff was very kind, helpful & efficient. Pricing was more than fair for the thorough, professional service that we received.
