Dr. Drew is the real deal. He understands the process and will let you know whether or not a qualified nexus letter can be written for CFR 38 standards. I was denied for my shoulder condition, when I read the decision letter, I saw his opinion was not taken into consideration. After doing a high level review, his nexus was the ONLY REASON my bilateral shoulder conditions were service connected. I also have a Bilateral Knee and Sleep Apnea claim still pending. I will be sure to upload screenshots of that as well. Don't hesitate!
