Dr. Catherine Boyce

Dr. Catherine Boyce

No one else really relates to what you’ve been going through and it’s taken a toll on you physically and emotionally. For over 25 years, Dr. Boyce has helped women and others who have felt isolated, anxious, and overwhelmed in their lives to find more happiness, satisfaction, and self-acceptance. She specializes in working with people who are struggling with chronic pain and GI distress and is honored to collaborate with Dr. Drossman’s patients as she helps them to heal their past and present hurts with Cognitive Behavioral Therapy and Clinical Hypnosis.

Therapy or counseling doesn’t have to be scary or intimidating

Dr Boyce works hard to understand who you are and what your struggles have been.  With this knowledge, she will create a safe environment where you will feel more connected than ever because you will discover you aren’t alone.  You will learn concrete techniques to relax and release the pain, as the body and the mind are intricately connected, and you will use these techniques to feel stronger, emotionally and physically. You will also learn to identify unhealthy thinking patterns and explore alternative ways of coping so that you can feel more in control of your health, life and choices.

Dr Boyce is accepting, healing, funny, and down to earth. In her practice, she will encourage you to look outside of yourself to see you are not helpless and to look within yourself to understand patterns of behavior and thinking that may be interfering in your life, relationships and choices.  With therapy and coaching you can become more aware and accepting of yourself and others. This self-acceptance will reduce stress and anxiety so that you can feel empowered to take on new challenges and create a more meaningful life for yourself that is not all about pain.
