    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.

    Treatment Specialties

    Dr. Luke Bigler is a licensed psychologist who is experienced in assessing and treating a wide array of mental health disorders. Through Dr. Bigler, education, training, and experience, he provides specialized assessment and treatment mental health services for the following:

    • Substance and virtual addictions (smartphones & video/computer games)
    • Teens and young adults
    • Dual-diagnosis treatment for underlying mental health disorders that have contributed to chemical dependency
    • Treatment for the specific challenges men and women face in relationship conflicts resulting from addiction or other mental health challenges.
    • Professionals seeking mental health services
    • Family members of loved ones with mental health struggles, with an emphasis on building healthy communication and boundary setting skills
    • PTSD and other trauma related disorder treatment

    Dr. Bigler also specializes in the assessment of substance use and cooccurring mental health disorders. Often, many mental health symptoms can be overlooked or misunderstood by psychologists or therapists if they do not have the training or experience with substance related dual-diagnoses. Dr. Bigler’s training years at Hazelden Betty Ford provided him with the education and experience necessary to accurately diagnosis and treat substance and other cooccurring mental health disorders.

    Parent/ Family Support

    Supporting loved ones with addiction and/or other mental health challenges can be difficult and overwhelming. Dr. Bigler provides counseling services and workshops for those who support others, focusing on setting healthy boundaries, assertive communication skills, and reducing care taker burnout. Just like the airlines teach us: we need to put on our own mask before helping others with theirs.
