Interface Designer. User Researcher. Product Manager.

Hello. I'm Daniel Ritzenthaler. Most people call me Dan or Ritz. I've been a designer since 2002. Along the way I've explored several research and management roles.

I'm a Senior Manager, Design at Iora Health. Our web/software group is small enough to require wearing several hats. I also design interfaces for a development team and recently managed a development team. Previously, I joined HubSpot as the second designer. I helped establish an early design system and build their original design team. I left shortly before the company went public.
