About Us

Your First Step to Wellness

Behavioral Wellness Clinic (BWC) clinicians are independent psychotherapists and mental health professionals practicing at a professional facility in Chadds Ford, Pennsylvania and Mansfield, Connecticut. Each clinician specializes in several different areas of counseling and mental health care, maintaining the highest professional standards.

BWCC therapists have a cognitive-behavioral orientation, which means they tend take an active approach to treatment. Therapists use proven techniques to facilite progress and help clients meet individual goals. It is important to us that clients understand how therapy will help them and what to expect. Our therapists will take time to explain their conceptualization of the problem and how treatment will work for you.

Anyone struggling with anxiety, phobia, traumatic memories, OCD, or related conditions can benefit from the services of BWC therapists. Additionally, individuals seeking counseling for interpersonal issues may experience positive changes in their intimacy, communication, and other obstacles that may interfere with relationships.
