Invisalign Impressions :The orthodontist I want to use does not have iTero Scanner. What options do I have?

The Orthdontist came highly recommended so I have great faith in him. However, this might sound trivial but I've got some kind of "sensory" issue so the thought of having impressions done has me stuck. What options do I have? Could this orthodontist send me somewhere that they use an iTero to have the scans made? I'd gladly pay extra for that option. I've watched many videos of people getting impressions done in the hopes of desensitizing myself but...it's not working. Thanks.
