Today insurance companies make it harder than ever to successfully file claims for whiplash injuries. But at B2Y, you’ll find a scientific, measured approach to getting the compensation you deserve.


With much of her training completed in Canada, Dr. Natasha Williams is a member of a medical community that continually sets the bar for understanding whiplash injuries. Dr. Williams draws from a broad array of the latest and most effective treatment methods. She also understands how to document your injury in a way that makes it easy for insurance companies to provide adequate compensation.

At the heart of Dr. Williams’ treatment philosophy is a deep understanding of and adherence to the Croft Guidelines for Cervical Acceleration/Deceleration (CAD), commonly known as whiplash. It lets her comprehensively understand your injury and the suffering it causes, as well as explain to insurers what you need to return to pain-free living.


In order to establish standards for an injury that’s often difficult to classify, Canadian chiropractor Dr. Arthur Croft in 1993 published a set of guidelines for cervical acceleration/deceleration (CAD), commonly known as whiplash. Today, these guidelines are not only widely accepted by the medical community, but by insurance carriers as well. Training in CAD guidelines is extensive and rigorous, but it lets qualified care providers more effectively diagnose patients and document injuries for insurance companies.

That means important factors are scientifically documented, including the severity of your injury, how much care you need and for how long, and any additional conditions that might complicated or prolong your recovery. In less scientific terms, your whiplash claim is more likely to be successful because it’s based on widely accepted standards.


At B2Y, the details of your treatment and are recorded in minute detail. It lets Dr. Williams more effectively map the steps to recovery and document your pain and suffering. The following are just a few examples of how Dr. Williams applies the Croft Guidelines for CAD.
