Meet The Doctors

  • Dr.
    Thomas C. Mattheson

    Dr. Thomas Mattheson joined Blackman Family Chiropractic in 2010, where he worked side by side with Dr. Michael Blackman. After working with Dr. Blackman for over 8 years, Dr. Mattheson purchased the practice and building in 2018 from Dr. Blackman, who continues to work in the building doing Clinical Applied Nutritional Counseling.

    Dr. Mattheson was born and raised in Andover, MA. He attended the University of Syracuse in NY, where he received a B.S. in Biology Health Science and an A.S. in Psychology. His choices were to go on to medical school or look for alternatives in the health profession.

    In 1984 Tom's father had an accident, falling 18 feet off a ladder while working. He fractured his spine at multiple levels with severe disc herniations. He was told by orthopedic surgeons that surgery was inevitable and that 100% recovery was very unlikely at the time. Hoping to avoid surgery, he began seeing a chiropractor. After several months of chiropractic treatments and exercise to strengthen his spine, the pain had finally and he avoided surgery.

    Dr. Mattheson's goal was to become a heart specialist after completing his degrees at Syracuse University. After his dad's experience, his dad asked him, 'Tom, why haven't you thought of becoming a chiropractor?' The idea changed his life forever, and Dr. Mattheson graduated close to home at the University of Bridgeport, College of Chiropractic in CT.

    Dr. Mattheson has been practicing for 10 years now and continues to follow his true passion in life by healing and making a difference in the lives of others all around the seacoast community. Dr. Mattheson states, 'I look forward to seeing new and previous patients, continuing to play a role in everyone's health care. It truly is a pleasure and honor to continue to serve the Greater Dover Community after so many years now. We would like to welcome you all into Mattheson Family Chiropractic. Cheers to your health!'

    Lee Clouthier
  • "It has been 22 years now. I hurt my back at work. The pain was unbearable. I had never experienced anything like it before. A friend of mine asked his Chiropractor if he knew anyone in my area that I could see. He only gave one name. Dr. Blackman. Before I knew it, Dr. Blackman called me on the phone, on a Sunday night no less! He told me to come in the next day and he would examine me. But it was the following sentence that meant the most. “If I can’t help you, I will at least point you in the right direction” What more could I ask! So started a long journey. 5 days a week, then 4, then 3, then 2, then once a week. Now, I go once every 3 weeks for general maintenance. Thanks Dr. Blackman to You and your great staff for all your great care. The one thing about back pain is that recovery is slow. You have to be patient and trusting. Remember, taking pain pills are not a long term solution! I highly recommend Dr. Blackman and his staff!!"
