Here at American Artificial Limb, our team treats every client as family. We take the time to understand your individual needs and goals to provide a service that is educational, caring, and motivating. Our small, specialized clinic allows us to focus more on each individual patient and their specific needs. AAL has led the Seattle metro area in post-operative prosthetic management since 1968 and continues to be at the forefront of prosthetic and orthotic technology as it rapidly improves. Join our many dedicated clients and expect nothing less than positive outcomes. We can fit patients into our schedule quickly for any urgent evaluations or follow ups. In-house fabrication allows greater attention to each device, leading to more accurate and effective results.
