2021 AASV Annual Meeting Program

"Navigating the Future ... Together"

February 27 - March 2, 2021
Program Chair: Dr. Mary Battrell

The 2021 AASV Annual Meeting will be conducted virtually in Central Standard Time (UTC-6).

The majority of presentations will be prerecorded and made available for viewing during the scheduled time in the program, with the speakers present to answer questions via live chat. Once released, the presentation recordings will remain available for registered conference attendees to view at their convenience until April 30. Yes, that's right -- you'll have 60 days to take in all of the continuing education the conference has to offer! And that's not all...

Virtual Conference Bonus: One price per day provides access to ALL of that day's concurrent pre-conference seminar presentations, enabling access to the content of five seminars for the price of one! (You must be registered for the main conference to register for the seminars.) While the speakers will be available for live chat Q&A only during their scheduled presentation time, the presentation recordings will be available for viewing by seminar registrants until April 30. What a deal!

A few key events will broadcast live, including the Foundation Luncheon, Monday morning General Session, Monday luncheon, and Tuesday morning Business Breakfast. Another change: the traditional AASV Awards Ceremony will be the live Grand Finale to close the meeting after Tuesday's General Session concludes at noon.

Tech Tables exhibits, poster presentations, and the veterinary student oral and poster competitions will continue to be an important part of the conference. There will be plenty of opportunities to interact with fellow attendees in group or one-on-one chat during the presentations - or to reach out to attendees or exhibitors to schedule a meeting. Contests and giveaways will entice you to explore the conference site and become familiar with all that it has to offer. Don't wait - Register today for the best virtual meeting AASV has ever held!

Seminar #2: Navigating Leadership: Becoming and Being a Vet CEO
Seminar chair: Sarah Probst Miller

Leadership sometimes finds us, and at other times, it is something we seek. Perhaps we might even self-proclaim and become an entrepreneur of our own company. Our DVM degrees teach us how to diagnose and problem-solve, but alongside these skills, what else is needed to be a good leader? How do we sharpen our leadership skills to become better leaders and/or position ourselves to be chosen for leadership positions?

The objective of this seminar is to be a leadership whetstone for veterinarians in any phase of their career. We have asked our speakers to share scenarios and lead interactive discussions to help each other sharpen our leadership skills.
