The book that most informs Kat's thinking is Man's Search For Meaning by Viktor Frankl.  She also enjoys the work of Irvin Yalom. The personal experiences that Kathryn draws from in addition to her clinical training and experiences include divorce and loss of a parent.

Kat says, "We all can benefit from therapy. Therapy should be a good experience to explore yourself and get to learn more about yourself.  It should also be rewarding, as you learn new ways of thinking. I believe in making the therapy process enjoyable and something you want to attend. I like to challenge people and help them grow emotionally and mentally."

Kat is also a coach, and can work with all USA clients on ADHD issues, career or nutrition coaching!  Check out her career coaching page here, and her nutrition coaching page here! Click here for more information about coaching vs. therapy.
