Profile bio

About Mattie Winowitch

👋 Hi! My name is Mattie, and I'm a communications professional based in Pittsburgh, PA.📎 JOB EXPERIENCE I have 5+ years of communications experience. I currently work as the Global Communications Manager at Telesign, a digital fraud prevention company. Within this role, I manage our social media channels, support executive comms, and collaborate with our HRBPs to support employee engagement efforts. My biggest accomplishment was implementing a B2B social media strategy (on LinkedIn) that doubled our average engagement rate and gained us 30K+ followers within two years.Before my role at Telesign, I spent several years doing similar work within health care. Most recently, I worked for UPMC Enterprises, the venture capital arm of the University of Pittsburgh Medical Center. Between complex medical terms and intricate technologies, I've become a pro at taking complicated subjects and turning them into bite-size nuggets of knowledge that everyone can understand.❤️ WHAT I CARE ABOUTWhen my heart is in the work, I'm unstoppable. I am especially passionate about environmental consciousness, "slow" fashion, women's health, and DEI efforts. On a tactical level, I believe in putting employee advocacy at the center of any social media strategy. Employees are your company's biggest fans (or at least they should be). I like to help empower employees to embrace their online personas and give them the resources they need to share the brand story with the world.🎓 EDUCATIONI graduated from Waynesburg University in 2019 with a B.A. in Communications (Print Journalism and Public Relations). I went on to receive my M.A. in Communication Technology (Social Media) from Point Park University in 2021.

Listed skills include Newswriting And Reporting, Feature Writing, Covering Regional News, Writing Articles To Deadline, and 10 others.
