Harmony Sullivan, PsyD

licensed psychologist

am a Clinical Psychologist working in both individual and couples therapy using Cognitive Behavioral, Emotion Focused, Psychodynamic and Interpersonal therapies as well as Mindfulness exercises.    I believe we are all capable of changing our lives to feel happier more of the time. Perhaps you are struggling with a big transition, such as the death of a loved one, marriage or divorce, having a child, changing careers, or coming out. Or maybe you feel stuck and you're not sure why. New clients often say that they are frustrated because they would like to feel happier but can't seem to figure out how. Therapy helps people break out of the rut and find new ways to achieve contentment.
