Marcia Grennell, PhD

I am a licensed clinical psychologist with over 25 years of experience helping adults, children, and families cope with a variety of difficult issues in life. My special interests include working with anxiety, depression, and loss. I also help children and parents deal with changes brought about by separation, divorce, and remarriage. My treatment approaches are cognitive behavioral therapy and longer-term psychodynamic therapy. In addition to therapy, I offer psycho-educational assessment of learning problems and attention deficit disorder in children and adults.
