“Kathryn has been communicating very well and has been very forthright with me.”


“Kathryn has great bedside manner. She provides supportive communication outside of just the facts of my case. Kathryn is supportive emotionally, provides encouraging guidance, and her customer service level is through the roof. She not only supports me through goal orientated tasks, but she also helps him to stay in a decent place mentally. … For the last 7 years I have been very distrustful due to the experiences with the opposing party.
