Success Stories
“My 13 year old daughter started seeing Dr. Vaughan because her TSH was 9.9, which is a thyroid test. She was feeling tired, body aches, and wasn’t eating much. A family member referred me to Dr. Vaughan. She spoke very highly of how she had helped her mother. Dr. Vaughan ran many test, in which she discovered my daughter had auto-immune thyroid. I have thyroid disease, on medications for years. She also tested my thyroid, I was also auto-immune thyroid. She worked with her and really the whole family educating us on the causes thyroid disease.. After her first blood test her TSH went down to 3.1. My daughter began to act like herself again, eating and playing as she did before. Dr. Vaughan really cares about her patients and their results. She’s a great doctor I would recommend her. I feel better than I have in a very long time.” – Malerie J.
“I have been on thyroid medications for almost 20 years and on diabetic medications for 15 years. It seems that the medications continue to increase, while my symptoms worsened. I have rheumatoid arthritis, with pain through out my body, fatigue and feeling not as sharp as I was in the past. I began to see Dr. Vaughan and within a few weeks I noticed an increase in energy. My diabetic medications began to drop. My weight began to drop. I have fought losing weight all my life due to my thyroid issues. My A1C was 8.9 when I started, with 5 mg glipizide, 2000 mg of metformin, 150 Levothyroixin, and 40 mg 3 times a day of Simvastatin. Six months later I am proud to say I have more energy than ever. I lost 35 pounds. My A1C is at 5.6 and off all diabetes medications, off my statin medication and my thyroid medication dropped down to 25 mg. Dr. Vaughan helped me realize I also have auto-immune thyroid, and how to control my auto-immune flare ups from happening. If you want to be healthy or get support out of your disease to a better place, go to Dr. Vaughan. Stop waiting. Your health will only get worse if you don’t address it.” – Karen C.
“My wife sees Dr. Vaughan, in which she continued telling me I need to go see her to get help with my diabetes. She had seen me struggle with it for 10 years. I am only 54 years old, my health started to deteriorate. I finally went to have a visit with Dr. Vaughan. I was really impressed by her knowledge and her approach. My A1C was 10.4, on 1500 mg of metformin a day. Immediately in the program my fasting blood sugars started dropping. My head wasn’t as foggy and I wanted to go work out because I had more energy. She ran diagnostic test and discovered I also had a thyroid issue. After working with her and doing as she asked my A1C is now 5.2 on no medications. My thyroid is back in balance. I have my life back. Thank you Dr. Vaughan.” –Tim L
