The Best!
We hired Kim for a custody case for our 2 year old Granddaughter , after some other lawyer we had screwed everything up . She came right in and took over in the middle of a nasty battle. And proved to the court exactly what my granddaughters best interests where. She did what she said she would do and we will never forget her saving our granddaughter from a life of horror. We are so grateful to have met Kim !!!

Exceptional, Outstanding, Superb!
I have used Kim twice in my Child Custody, Visitation & Child Support hearings. She is knowledgeable and reliable, but also cared about the client (clients) and their best interest. She can also be aggressive if need be. SHE IS MY ROCK! I will use no other attorney!

fast, reliable and sympathetic
Kim was a pleasure to work with, answered all my questions and listened to all my concerns. She was sympathetic and easy to talk to. She was very flexible about meeting times and was always there when she said she was going to be. I would definetly use her again if I ever needed to and recommend her to others

Great job!
Mrs. Guay helped me through the family court process regarding my son. She in formed me of documents I would need and took the time to explain each one to me. She was very knowledgable with any questions I had! Even though this is an emotional time in my life she made me feel confident and secure in the process moving forward!
