Meet the Doctors

  • Dr. Erica O'Brien

    Hello, my name is Dr. Erica O’Brien. I was first introduced to chiropractic at the age of seventeen, after a 3-year long stint of off-and-on lower back and leg pain. My parents and I had previously explored several other avenues of treatment for my symptoms, with few lasting results or even temporary relief. After a few chiropractic visits, my body responded in a positive way to the treatments. The doctor also taught me how chiropractic works by clearing the nervous system of interference, so that the brain and the body are able to communicate with each other as efficiently and effectively as they can.


  • Dr.
    Heather Thompson

    Dr. Heather Thompson graduated from Life College West in 2015.  Dr. Thompson has been part of the Affinity Chiropractic & Wellness team since  summer of 2019.  She displays the highest level of chiropractic skill with every patient she treats, and is warm and personable, to boot. 


Reviews By Our Satisfied Patients

  • "Everything about Chiropractic office is top notch. Dr. Erica O'Brien came highly recommended and now I know why. Appointments were always on time; in fact, most of the time they were ready for me BEFORE my appointment time. They were definitely:: listening & understanding --
    handled everything with gentleness, & kindness. Great atmosphere."
    Betty E.
  • "Absolutely the best doctor around! I have been dealing with tendinitis in my foot/leg and after spending months and thousands of dollars dealing with doctors and physical therapy, Dr. O'Brien was able to ease my pain and loosen my muscles. She has given me more flexibility and I look forward to being pain free soon. She is attentive and responds to your specific needs. I love the whole staff at Affinity as they truly work to heal you by providing the best service and treatment available! Thanks Affinity!"
    Juanita Y.
  • "Upon my initial visit, I was greeted by a very welcoming staff. After I completed my initial patient paperwork, everything flowed seamlessly. The specialist, Dr. Erica O’Brien, asked a detailed string of information to see why I was here, what was bothering me, and the activities I preform on a regular basis; that could contribute to the discomfort. Once that was done, an X-ray was preformed to check my alignment, and for possible damage.

    When it came time for the actual treatment, it was professionally done and I left satisfied. I’ll definitely come back for a follow up. Great facility."
    Jonathan M.
  • "The whole staff is really friendly and helpful. Dr. Erica has magic hands and can cure the world. 10/10 would recommend. :]"
    Hilary G.
  • "I’ve been going to chiropractors for more than a decade due to a minor back injury. I’ve seen quacks who tried to scare me to death. I’ve seen doctors near retirement and they care but sometimes phone it in. And I’ve seen some that make me leave feeling worse than when I came in. I started bringing my son to see Dr. Thompson at Affinity and seeing her work with him reminded me what I missed in a good chiropractor. I’ve started seeing her, too, and I’m 100% happy with my results. Dr. Thompson makes you fee comfortable, welcome, and we’ll cater for. I highly recommend Affinity and Dr. Thompson!"
    Euph R.
  • "Was in need of chiropractic care due to immobility around the holidays. Affinity was taking new patients, they honor my insurance, their rates are very reasonable and after 4 treatments, I am walking and almost pain free. Dr. Heather is generous with teaching about the issues, how to resolve them, stretches and has relieved major issues. Went there on a recommendation from a former neighbor and I am glad I followed through."
    Terry S.
  • "Dr O’Brien is really knowledgeable and knew all the spots where my legs were tight. I had such a great experience and she helped me with Webster technique and turned baby in a couple sessions"
    Val M.
  • ""I went to Dr. O'Brien in August with terrible nerve pain running down my leg. I could barely stand (and sitting and lying down weren't very comfortable either). An MRI determined that it was a bulging disc causing the nerve pain.""
  • ""I had this same problem 6 years ago and had to have surgery to eliminate the pain. Dr. O'Brien suggested that I try spinal decompression this time around.""
  • ""I'm so happy to report that 3 1/2 months later, I am now completely nerve pain free! Dr. O'Brien and her spinal decompression machine saved me from having to have an invasive surgical procedure. Thank you, Dr. O'Brien!!!""
