I renewed my certificate here last week. The service was excellent and the doctors were far less intrusive and inquisitive than the doctors who renewed me the last two years. Oddly enough those annoying doctors were the same ones I saw before. This issue of paperwork gone askew....Well I will see what happens with my own. If you have your own medical records that you are willing to use you may be able to get certified for less money, however you must ask yourself what is the value of your time and do you really trust your doctor and insurance company.???
