2021 NDAL Annual Symposium

UPDATE: NDAL’s 2021 Annual Symposium will be in webinar form.

Normally held every January in the Philadelphia area and New London, CT, NDAL’s 32nd Annual Symposium will be moved online due to COVID precautions. While we are deeply disappointed that we will not be able to meet with everyone in person – to see many familiar faces as well as new ones – we are grateful to be able to present our Symposium via live webinar sessions.

Stay tuned in the coming weeks for finalized Symposium webinar dates, which will be around late January – early February of 2021!


The NDAL Conference continues to be the highlight of my winter – it’s the tangible beginning of the landscape season charging us with enthusiasm and expanding the breadth of our knowledge base!
