Judge Mary Celeste is extremely knowledgeable in many areas of substance-impaired driving. I’ve had the pleasure of working with her on multiple occasions and each experience has been delightful.

Judge Mary Celeste (ret.) has a wealth of knowledge regarding the marijuana industry and it showed with her presentation at the 2016 DATIA Annual Conference. She provided our attendees with valuable, timely and insightful information on how marijuana legalization is changing the landscape of America. She’s been a pleasure to work with, a great resource, and we look forward to working with her in the future!

NADCP RISE 2021
This past fall, she presented on New Marijuana Laws in New England. Some comments included “Facilitator was extremely knowledgeable, a great presenter and enjoyable also was able to present information and history of laws in a clear, organized manner; she kept her presentation flowing while allowing for questions and discussions”. Because her evaluations were among the highest and her subject matter relevant –she is indeed a content expert- we would welcome her back again at training events or our annual conference.

She presented the information in an entirely factual manner without any opinion presented. I would LOVE to see another presentation by her around the topic of cannabis in the future
