Angela, I don’t specifically “specialize” in strengths psychology” however, with my clients who I coach, I request that all of them read Strengths Finder 2.0 written by Tom Rath. I also ask that they complete the assessment that is found in the back of the book.
As a Licensed Wellness Coach through Wellcoaches, I have been trained to coach my clients focusing on what is working in their lives.
Another site that I utilize is www.authentichappiness.com This site “is the homepage of Dr. Martin Seligman, Director of the Positive Psychology Center at the University of Pennsylvania and founder of positive psychology, a branch of psychology which focuses on the empirical study of such things as positive emotions, strengths-based character, and healthy institutions.”
I believe you will find it quite helpful.
