Dr Fife spent years testing; comparing, as well as trial and error with all of these recommendations. He also spent time in offices picking other practitioner’s brains and these listed companies are who he trusts the most. He also likes them for fair pricing and in-stock, as it would be very difficult to stock up all of these companies in the WWC office area, Feel free to ask him questions on these recommendations at your appointments. He is always happy to help you figure out what is best for your health and keeps you out of the office long term and on the wellness plan you are aiming towards!
