Tanya J. Colledge, Psy.D.
Licensed Clinical Psychologist

Tanya J. Colledge, Psy.D.

Dr. Colledge received her Doctorate in psychology in 2001 from Pepperdine University in California. She completed her internship and residency in Washington DC and Northern Virginia before moving to Utah. She has worked with bariatric surgery patients since 2003. She is committed to helping patients understand any issues they may have related to eating and how to better cope with and make positive behavioral changes that will help them be more successful with surgery.

What to expect from the psychologist

Our psychologist will help guide you through any psychological issues that may be impeding your ability to be successful with surgery. Pre-operatively, she will consult with you and examine psychological testing that is completed to determine if there are any additional issues that need to be addressed prior to surgery. She may make recommendations to you on other work that can be completed to help you become more insightful about your eating habits and psychological issues. This may help you be more successful with surgery. Aside from the evaluation appointment, she is available for assistance, if needed, with any other issues that may come up related to surgery and psychological changes that can occur.

BMI requires all patients have a psychological evaluation, including testing prior to surgery. Dr. Colledge is an independent psychologist we have partnered with for the convenience of our patients to be seen in our office. She understands what insurance companies require which helps the authorization process. Please be aware that she does not participate in insurance plans so the evaluation costs is $250 due at the time of service. You may attempt to find a psychologist that may be covered by your insurance but we highly recommend her to our patients because of her experience with Bariatrics.
