    Every successful journey requires a clear and concise path, mental healthcare is no exception.

    An accurate diagnosis is paramount in healthcare treatment. However, many mental health symptoms that comprise one disorder are also found in others. Psychologists have extensive training in both treating and diagnosing behavioral and cognitive illnesses. Starting treatment with a clear and concise path, often results in treatment being more effective, requiring fewer sessions. Ultimately helping the individual find the inner peace they desire.

    When substance or behavioral addictions are present, this typically presents significant diagnostic challenges. I decided early on in my education that I wanted to become an expert at understanding how to help individuals who struggle with both addictions and other “co-occurring” mental health illness. My education and training include specialized course work in addiction treatment, a research dissertation on comparing substance use treatment programs based on gender and age, and I completed an advanced fellowship at the world’s foremost substance treatment center.

    My education, training and professional experiences have taught me that life’s path is not always linear or simple. Sometimes, even those will great emotional resiliency need help to work through some of life’s more challenging problems. Everyone has battles to fight and hurdles to overcome at some point. Whether you struggle with anxiety, depression, low self-esteem, or any other mental health issue, you should know that there is hope for a better tomorrow.

    Diagnostic Assessment

    As with any treatment, understanding and defining the root of the problem, is imperative to effective treatment. As a psychologist, Dr. Bigler received the education, training, and experience necessary to accurately diagnose mental health illnesses. Those individuals who struggle with compulsive or addictive behaviors may often be misdiagnosed as the effects of substances use and other unhealthy behaviors can add complexity and uncertainty to the diagnostic picture. This can often result in not achieving the desired therapeutic outcome. Our initial session (also referred to as an assessment) will comprise of three parts: Getting to know you, identifying the problem/s, and collaborating on the treatment recommendations that will ensure the best outcome possible.
