I consider myself to be an adventurous creative type, and people centric. I was raised to make my own decisions, and was the first to venture out and leave home when I joined the Military at the end of my senior year in high school. I wanted to experience the world a bit “on my own” before going on to college. I ended up getting a lifetime of experience in the three years I served, because I found myself working on a medical ward on which many people were quite ill. Dealing with life and death situations at that young age brought a keen insight and understanding that only comes with realizing how temporary life is, and how precious life and the ones around us are. I was put in positions of leadership, which brought out talents I would not otherwise have discovered in myself. Following that, I went on to college; studied first the classics (Latin, Aesthetics, Ancient Chinese History and the like), followed by study of Human Development and Learning, and became a certified teacher. When I felt fulfilled from working in that field for over fifteen years, I then started my creative endeavors full time, in 2000. I learned to do film work at The People’s Channel in Chapel Hill, NC, then moved on to oil painting, where I sold eight large paintings my first year. I went back to school to study interior design at Meredith College, which led me to my true creative passion, which is clothing design, because it is creative and essential, solves problems, and answers real human needs - practical and useful.

I return the favor to Mariangela.

Mariangela and I first met on September 11, 2012, which was my second day in North Carolina as a Visiting Scholar at The University of North Carolina at Chapel Hill.  The previous night I had stayed at the Carolina Inn Hotel.  We met as I was walking through Carrboro on my way to the apartment I had obtained.  Seeing that I was rolling a large suitcase down the sidewalk, Mariangela asked if I needed a ride.  It was going to be a 2-mile walk, so of course I said yes!

We stopped at Weaver Street Market, chatted for a while with her husband who was there, and they drove me to my new apartment. After that she helped me get my apartment set up and get adjusted to the good life in North Carolina. She invited me to seasonal family gatherings and to meet her good friends. We attended Tar Heel basketball games together.  This turned her into a big Tar Heel fan!  Mariangela visited Tokyo for her first visit in 2019.  We are looking forward to developing Guarantee Happiness into a business that serves people’s need for comfortable clothing that is both stylish and unique.  Stay tuned!

Guarantee Happiness is a brand with a serious mission and a large dose of meaningful humor.

Nobody can Guarantee Happiness, of course, but we sure include it as we create chic-fun-comfortable clothing while also working to incorporate delightfully interesting ways to reduce waste in the apparel industry. Our first mission along that lines is to include (up cycling) in Pop-ups: We participate at FUN RUNS and MEANINGFUL FUND RAISING ROAD RACES/WALKS across the USA and beyond, and add skirts (made from clean industry left-overs and over-runs) to tee shirts (Tees + Skirts = Tee Skirt Dresses) which are made for the events to AMPLIFY the fun, comfort, and "cool" factor for event tees! We also make "high end" Tee Skirt Dresses which satisfy the desire for dressier play clothes.
