About Jessica Diaz
I have spent fifteen years helping people understand their bodies. Human Design is the system that finally pulled it all together.
I am a Certified Human Design Coach, Master-level Reiki Practitioner, Certified Biofield Tuning Practitioner, and Certified Personal Trainer. This is the work my whole career has been building toward.

My story
I started my career completely focused on the physical. Personal trainer, barre instructor, certified coach. I knew how bodies worked mechanically and I was good at it.
A few years in, at 36, I had a stroke. And everything I thought I knew about the body stopped being enough. Recovery forced me to stop pushing. For the first time I had to actually listen to my body instead of override it. Physical fitness had always been my foundation but I started to understand that the body operates on more than just the physical level.
I went deeper. I trained in Reiki, then Biofield Tuning, then meditation. I began working with energy the way I had always worked with muscle and movement. Each piece added something. But it was Human Design that brought it all together. It was the manual my body never came with. It explained my energy type, my decision-making authority, why certain things drained me and others lit me up. It connected the physical and the energetic in a way nothing else had.
I got certified. I started helping others read their own charts. And what I see over and over again is people finally exhaling because someone just explained them to themselves. That is what this work does. That is why I do it.
