For his contributions to cognitive and neuropsychological research, Bill won a Student Research Award by the National Academy of Neuropsychology in 1995 as well as the Nelson Butters Award for Research Contributions to Clinical Neuropsychology in 2001, a distinction for being an author on what was considered the best and most significant research article published over the past year in the journal Archives of Clinical Neuropsychology.

    When he is not working, Bill loves traveling to the beach, hiking in the desert and spending time with his friends and family, especially his wife, his father, and his dog Myrtle. Bill has also been known to crack jokes (often bad ones) on a frequent basis, obsess over sci-fi fantasy, and books and movies, listen to an eclectic array of music, and eat Southwestern and Mexican Food.

Our Clinic

Here at River City TMS, we’re not just a clinic; we’re a community. We are locally owned, operating with care and compassion in Spokane, Washington since 2020. We have a knowledgeable and skilled team of mental health professionals, including a clinical psychologist with 30 years of experience as well as a board-certified psychiatrist with specialized training in TMS for over a decade.

We use the FDA-approved Neurostar TMS device, a proven therapy for treatment-resistant depression since 2008. And the results speak for themselves: 83% of patients see clinical improvement, and 62% achieve complete remission.

Not all TMS treatments are the same and that is why we have chosen the Neurostar TMS device, which is the #1 choice by doctors for treating depression and has the largest clinical data set backing its efficacy and safety.

We understand that sometimes medications and therapy are just not enough and patients need alternative, non-invasive treatment. TMS is not just a treatment, it’s transformation that produces long-lasting results.

We are dedicated to providing exceptional, evidence-based care to our patients that has been backed by research. Our team of highly trained and trauma-informed mental health professionals work together to provide a comprehensive, personalized approach to care that takes into account each patient’s unique needs and circumstances. We are committed to providing a warm, welcoming, and inclusive environment where all individuals can receive the care and support they need to find relief from depression, anxiety, obsessive compulsive disorder (OCD), and post traumatic stress disorder ( PTSD).

We believe that mental health is an essential component of overall health and well-being, and we are committed to empowering our patients to take an active role in their own care. We work collaboratively with our patients to develop treatment plans that are tailored to their specific goals and preferences, and we provide ongoing support and guidance throughout their journey towards recovery.

If you are ready for a brighter tomorrow, reach out today and start your journey to mental health wellness with us at 509-992-0290.
