Heidi Kolman, LCSW

Heidi is a psychotherapist with over 16 years of experience working with diverse populations and age groups. She sees her role as that of "helper" on the road to healing, and uses tools such as art, drama, movement, insight, ego strengths, building healthy living habits, mindfulness, emotion regulation, distress tolerance and interpersonal skills to help others heal. She works with children and adults to increase awareness of the physical signals our body sends us to communicate needs, in order to meet these needs mindfully, compassionately, and most important, effectively. Heidi integrates the use of art, drama, movement & play when working with all age groups, as expressing what is not expressly available to the conscious mind is an invaluable experience.
