Formerly known as Christal Center, we have been providing wellness therapies for 30 years. Estabilshed in 1984 by owner Christal McIntyre, Christal Center was the original Massage Wellness Center in the Northland. Christal has spent much of her time educating the public on the many benefits of the human touch, energy balancing and wellness products. We are proud to still be going strong! We feel honored to have treated and guided so many clients to achieving their health goals & their highest good in life.

Our new name Tetrah came about while we celebrated our 30th anniversary. We wanted to celebrate our staying power and the many wonderful changes we’ve been making recently. The word Tetrah, to us, means coming from the first molecule of life, to create life, and to flourish to life’s highest good.
