David had read some of Leonard's publications including the study regarding problems with CBT when used with patients with ME/CFS. David also appreciated the research Leonard had done over the years examining case definitions. David believed that the work Leonard has done should be a foundation for how patients, scientists and government can collaborate and in particular, how patients can be part of the process as the decisions that are made do impact their lives. David and other advocates asked Leonard to be a guest speaker on a ME/CFS phone peer support group, based in North Carolina with callers from all around the country.
