Heidi Koronkowski

Behavioral Coach

Heidi helps people who have anxiety disorders by meeting with them on a one on one basis in their home or phobic situation. Working with Heidi in real life situations can be very effective. She teaches people how to confront and deal with their particular anxiety, phobia or OCD issue using behavioral techniques that she learned while completing her Behavioral Coach training at Anxiety Treatment Services with Dr. Dufford, Clinical Psychologist and Mary Szeles, Behavioral Coach. Heidi also draws on her own personal experience in overcoming severe panic and agoraphobia. Her goal is to provide hands-on, context-sensitive coaching aimed at helping others live symptom free.

Heidi had suffered with anxiety, panic and phobias for over 15 years. After finding limited success through talk therapy and medication she had a severe relapse and realized she needed to find a different kind of help. She found Dr. Dufford and Anxiety Treatment Services. After working with him and using his cognitive-behavioral tools and techniques, she has truly found freedom from anxiety, panic and agoraphobia.
Heidi has served as the Director of Early Childhood Weekend Ministries in Santa Cruz overseeing nearly 150 children a week. During that time she saw many children come into the classroom anxious and fearful being away from their parents for the first time. She successfully worked with these children to help them overcome their fears and anxiety.

Heidi also facilitates a Support Group for Parents of Transgender Children. As a facilitator, her coaching skills are put to work helping parents who are anxious about their own feelings and the transition that their children are experiencing.
Heidi was born in Santa Cruz and lived her entire life in the Bay Area. She has been married for 18 years and has three children.
