What Our Clients Say About Us

  • "Dr. Rankin and her staff are AMAZING!! Dr. Rankin is very thorough and takes the time to understand you as a whole person. My daughter and I have been patients of hers for years and she is definitely the best doctor around. I could go on and on about how awesome she is, but the quality that makes her stand out from all the others is her intelligence and persistence to treat you as an individual person."
    Adrienne L.
  • "Dr. Rankin provides an excellent service to my family. She is helping my younger son for years with different issues related to ASD and PANDAS with great results. She had helped me as well, after years of seeing endocrinologists for diabetes type 2 with no improvements, I asked Dr. Rankin to help me. I am happy to report following her recommendations I am down to only one med. We appreciate having a great caring doctor and highly recommend her."

  • "I find Dr. Rankin to be a very professional, personable, thorough and thoughtful person. I’m continually impressed with her knowledge of the newest and latest products and treatments in this industry along with her understanding of my condition and how to best align specific products in my treatment plan to bring about the desired results. Dr. Rankin is the best! She doesn’t forget to provide me with information she thinks can help me despite that she may not have it on hand at the time of my appointment, but always comes through shortly after as promised with the information she wanted me to consider via email. Just amazing!!"
