Devin Smith

Devin Smith


Corvallis, Oregon

Hello! My name is Devin Smith and I have von Willebrand's Disease. I am currently attending Iowa State University pursuing a degree in mechanical engineering. Ever since being diagnosed with VWD at the age of 2, I have been involved with the community. I am looking forward to getting to experience many important bleeding disorder events, such as BDC, from a new perspective as a representative of NBDF and an adult rather than just an attendee. In my free time I enjoy hiking and biking.

Antonio Alexander

Antonio Alexander


Bloomfield, Connecticut

Hey there, I'm Tony, short for Antonio Alexander, a 20-year-old from the vibrant city of Hartford, Connecticut. Currently, I'm pursuing General Studies at Manchester Community College, exploring different fields that spark my interest. Besides being a college student, I am also a photographer and an aspiring creative. I took my passion for photography to the next level by establishing my very own photography company. Capturing moments and preserving memories in a unique way brings me immense joy. But my journey is not just about personal growth; it's about making a positive impact on the lives of others. That's why I'm deeply involved with various non-profit organizations that focus on providing opportunities to children who are passionate about photography, videography, and other creative pursuits. Empowering these young minds and helping them discover their talents is incredibly fulfilling. Ever since I was little, I've been an active participant in HFA (Hartford Fine Arts), and their activities have shaped my artistic spirit. Now, I want to give back to the community that nurtured my passions by becoming a pillar of support and a role model for other children. Together, let's inspire and create a brighter future for the community we hold dear.
