Our Purpose

Our purpose is simple—to celebrate life and to lift others.

When Roy and his wife established Learning Curves Adventure Tours, it was with the goal to combine their love of Harley riding with their heartfelt commitment to give back. What started as a relatively small endeavor has led to something exponentially bigger and better than they ever imagined—part of which is this book.

With this book, we hope to share important lessons we’ve learned on the hairpin turns and beautiful stretches of life.

And we want to help make a difference, donating the net proceeds to support medical and humanitarian aid in third-world countries where the need is dire.

Making a Difference

For years, both of us have been passionate about making a difference. Through Roy’s Learning Curves Adventure Tours and his nonprofit Smiles for Hope, we’ve been able to experience truly life-changing moments.

Our recent trip to the Dominican Republic

We’ve gained far more than we’ve ever given as we’ve visited remote areas around the world to deliver dental and medical equipment, help build schools, and share in the camaraderie and hope of new friendships.

With your purchase of the Learning Curves book and/or audio download, you’re now a part of the giving!  Net proceeds from this book will go to Smiles for Hope, helping to support humanitarian missions and delivering much-needed dental and medical supplies.
