Marci Nemhauser, Psy.D., C.L.C.

Marci Nemhauser created Professional Growth Services after over 20 years as a clinical psychologist because she was ready to change the way in which she helps others.  Marci is now retired from her work in Oregon. She was co-trainer in Growing Coach Certification for a few years and is still mentioned in our training program for coaches, as Cat and Marci worked together for years to train people to experience themselves as coaches.  We want to acknowledge that although she may not be in class physically, she has been a part of our coaching classes and development.  Although she is now retired, you may hear her voice in some recordings in Executive Coaching and Growing Coach Training.
