    Blaine Bettinger is my favorite presenter. He’s as clear, uncluttered and directed as I can imagine.

    I love the clarity and focus Blaine brings to every topic he teaches. Y-DNA has been a difficult tool for me to fully understand while working to identify my husband’s surprise paternal grandfather and his lineage. Blaine’s ability to teach in a clear, organized, and on-track way has given us real hope that we may still discover the surname and hereditary line.

    If only Blaine did every webinar on every topic what a perfect world of understanding genealogy and DNA would be. While I have not, and may not, submit a sample for Y-DNA testing, this webinar gave me a slight push toward doing so once I go back and view his previous webinar(s) on the topic. His presentations make learning enjoyable because he is a “teacher” and wants those viewing his work to come away with an understanding of the subject at a level where it all makes sense. Well worth the time spent.

    Blaine is always an excellent presenter. I was very glad to have a course being slightly more in-depth on understanding what is being presented with Y testing, and what can be derived from the results provided. You will find that further great strides have been made in some of the Y-haplo discussion groups on FTDNA that were not mentioned here (content for the next level up?), where the groups are then driving data and process items back to FTDNA and Y-Full.

    Thank you for making something that appears so complicated more understandable. I learned a lot but still have more to go.
