The Thunderbird clinic was started by Dr. Harold in 1999 and is now in the heart of Walnut Grove. Ideally situated in the Thunderbird plaza next to Shoppers Drug Mart and IGA on the second floor of the professional building above the Van City Bank. This clinic started from scratch as the Meinzer Chiropractic Clinic with just a couple of rooms and soon expanded into our current location and became the Thunderbird Wellness Centre. Now, with further growth, we are re-branding to Evolution Wellness Centres.

Again, a great group of diverse practitioners all with skills that may help you through your health issue. We would love an opportunity to have you try our services and help us continue to grow in the community.

I’ve visited Harold a handful of times and every time I do, he always eases whatever pain or stress I am holding in my back and shoulders. He is very professional and has an amazing sense of humour which I greatly admire. I would highly recommend Harold’s services and abilities.”  ★★★★★

I just wanted to thank you for the relief you’ve given me. After being sent for test after test and going from one specialist to the next, I was starting to lose hope. Nothing was discovered and I was beginning to wonder if it was all in my head.

A friend of mine, hearing about my symptoms of pain, numbness and tingling, suggested I go see Harold. After three visits, I noticed improvements. Everything he said made sense. I still have some pain but most of my symptoms have disappeared. I have more energy and a new lease on life! Thank you for your logical approach to the body and for fixing my “mysterious illness.”  ★★★★★

I’m probably like most people who put off doing anything positive with my health and well being because I just can’t fit it into my day. So needless to say, by the time I make that call to your office, I’m hurting badly! There are quite a few reasons I keep coming back to you:

  1. When I call, there’s always a friendly hello on the other end followed by an obvious dedication to getting me in as soon as possible. (Elaine is the best!)
  2. You all seem to work so well together to try and fix the problems. It shows up in how friendly you all are, how professional and bottom line is, I get better because of all your help.
  3. I do not hesitate to refer my friends or people I meet to your chiro/massage care as I truly trust you can make them better.

When I’m in need, I will always call your office first and you guys always come through for me!
P.S. Do Not Move Ever!

Thanks so much”  ★★★★★
