About Us

Active Family Chiropractic opened its doors on April 1, 2015. Dr. Patrick Trenary had been in practice for some years as an associate doctor. He took everything he learned and applied it to his new chiropractic care center, allowing the people in the Mason City and Clear Lake communities to benefit from his training and experience.

Keeping Your Best Interest in Mind

It’s our team’s goal to help everyone who walks in the door here. You’ll receive the highest level of service and get a clear idea of what chiropractic is and whether it can help you. There are no high-pressure sales tactics here; the ball is in your court, and you’re the boss. You can decide what you’d like to do, and we’re here to support you.

Your First Appointment With Us

When you first meet with us, we’ll dig deeply to get to the cause of your issues. In our relaxing atmosphere, you’ll know you’re in the right place to find the resolution you’ve been waiting for. You’ll be adjusted right away on your first visit, too, which means you won’t have to wait to start your healing.
MEET DR. TRENARY »


Dr. Trenary’s wife suffered from migraines for years. Since being under care, she hasn’t had a single one. Another patient had his neck adjusted and told Dr. Trenary, “I can see colors again!”

These are just some of the impactful stories we’re privileged to have played a part in. We see babies, too, who can get incredible benefits of care. If your infant or child has an ailment or challenge that makes you feel a little concerned, know we have the skills to gently evaluate them.

We’re proud to announce that we have been selected as the Reader’s Choice for Chiropractor’s Office by the Globe Gazette. Thank you to everyone who gave us your vote of confidence!

Convenient Hours

We have same-day visits available if you’d like to get started immediately. Plus, there are evening hours offered so that you can get in for an appointment after your workday or when your children are out of school. Contact our team now to book your time with us!
