Product Description

Known For: Kalispell/Flathead Valley location of Big Sky Ketamine Care, led by Dr. William Stratford — Montana’s ketamine pioneer with over 40 years of psychiatric experience.

HealingMaps Take: Big Sky Ketamine’s Kalispell location brings IV ketamine infusion therapy to the Flathead Valley, one of Montana’s fastest-growing regions. Led by Dr. William D. Stratford Jr., MD, FAPA — a board-certified psychiatrist with more than 40 years of clinical experience — this practice carries the distinction of being among the first to offer IV ketamine in Montana. Dr. Stratford’s decades of psychiatric experience bring a depth of clinical judgment that newer providers simply cannot match, particularly when it comes to complex cases involving treatment-resistant depression, suicidal ideation, and bipolar disorder. The Kalispell office serves patients across the Flathead Valley, including Whitefish, Columbia Falls, and Bigfork, eliminating the need to travel to Missoula or beyond. The mixed Google reviews (3.3 from 11 reviews) suggest some variability in patient experience, but the small sample size makes it difficult to draw firm conclusions. For patients in northwestern Montana, Big Sky Ketamine provides the closest access to psychiatrist-led IV ketamine treatment.

Patient Review

“Dr. Stratford’s experience really shows. He understood my treatment-resistant depression in a way that previous providers hadn’t, and the ketamine infusions gave me relief I hadn’t felt in years. The Kalispell location saved me from driving to Missoula.”
