  • Roberta Lynn Madow

    Ms. Sadler is a skillful advocate on behalf of her clients. She has impressed me over the years with her work ethic and her ability to advance her client's interests in court proceedings and through negotiation with counsel. I endorse this lawyer, and, additionally, I like her (which is not something I can easily say about all attorneys).
