Attorney Profile – Alison Keil


Keil & Siegel is a family-oriented law firm with uniquely close attorney-client relationships. We are here for our clients 24/7 and always offer, and find, that we can resolve differences outside of court where appropriate. We take the time to hear the entire history, and to get to know about the children and family before making legal decisions that can impact a client. My clients keep in touch with me years down the road and appreciate the closeness and careful decision making process. I am constantly referred to children, cousins, neighbors and friends through word of mouth. There is simply no stone unturned in each matter; my clients are my top priority. -Alison
