1992 Ive been using Dr. Marshall products as a patient, now 1999 forward a practitioner. For years I just emailed my list and Clive Buriski would fill my order and educate me. I do miss a seasoned practitioner on the other end of the phone. Ive personally done each protocol over all these years. When i just order, I am skilled in QRA, so I order, and if I add one more item, your online system defaults to my home address/pracice address. So I have to go back in and make sure its going to my client. I usually emal William about it, and he sorts out the detail, everyone is great at helping when something isnt right. If I start a full time QRA practice I would need immediate and correct service so I probably will start once I end up at my new residence. Sincerely, Suzanne Jennings,PT
