Meet Our Leadership Team

Brenda Preferred Headshot
CEO + Founder

Brenda Navin, RD

Brenda is the founder and CEO of Launch and is on a mission to make a difference in how healthcare is delivered. She likes to work hard and is up for any challenge, which usually means pushing a boulder up a big hill.

Brenda has over 20 years of experience in healthcare leadership and is a registered dietitian, and she believes food is the closest thing to a magic bullet when it comes to our health and wellbeing. She is sick and tired of “sick care” and works tirelessly to help people live happy, healthier lives because they deserve it. She loves being creative and has an endless list of ideas.

When not working at Launch, Brenda enjoys cooking, usually without a recipe, but has chef Jeremy on speed dial for when things go awry (perks that come with working with a chef). She loves being active and can likely be found at the gym way too early in the morning.

Chef Jeremy’s students love his sense of humor and engaging teaching style, and he definitely has a fan club. If you take a cooking class, you will be sure to find out what his kitchen pet peeves are.
