Important Conference Update

We would like to inform the PTCOG-NA community that the board is currently reviewing and finalizing plans for the 7th PTCOG-NA Conference to be held in Seattle. Due to the COVID-19 pandemic it is most likely that the event will be postponed to 2021. If opportunities remain to present abstracts this year the submission deadline will be extended accordingly.
