We do DNA education right!
We have taught more than 10,000 DNA courses.
To make DNA discoveries accurately and confidently, you need instruction designed for the way adults learn best.
You need our proven SPIN process:
- Study with expert teachers who break the science down into everyday language and step-by-step instruction–and give you time to process what you learn
- Practice on guided activities, with exercises and repetition so you can master new concepts
- Implement what you learn with your own DNA results, and get
- Next Steps based on your discoveries and goals–so you can keep building on your knowledge and skills!
We use this process in our Courses and Workshops. We also offer get-started solutions you can use to advance your learning independently: our popular DNA Testing Company Tours and Your DNA Guide–the Book.
