putting me back in medicine

As caregivers ourselves, we set out to help simplify the complexities of the medical world for parents and caregivers. Regardless of your child’s age or medical situation, keeping track of everything is hard. We built mejo to help keep your child’s medical and care information beautifully organized, tailored to your needs and easy to share. Our mission is our tag line - 'putting me back in medicine'.

our founders

In 2018, after 15+ years in Business Development, Marketing and Fundraising Ryan paused his career to become a Stay at Home Dad/Caregiver for his twin sons. One of his sons has an ultra rare genetic disorder called Costello Syndrome. He has experienced many situations in the healthcare arena. Managed countless specialists, coordinated surgeries, administered hourly medications, looked for answers and have heard "tell me about what’s going on with your son?” too many times to count. 

He started the concept of mejo a couple years ago via a PowerPoint while sitting in the NICU over 103 days. Over the years he's spoken with many caregivers. They all identify a need for a single tool to help them organize their loved one’s journey in a visual way. Most information is scattered across multiple medical record platforms that don’t speak to the caregiver in a way that makes sense.

A lot of healthcare is missing the human element. mejo is not just about medications, surgeries, height and weight. It also helps keep track of the things that make your loved one unique- knowing that he loves high-fives and the baby shark song or that he only eats through a g-tube is just as important as his medications or his blood type.

Ryan created mejo to be simple, high level and go beyond the chart. Whether you have one medically complex kid or multiple loved ones you're trying to keep organized, mejo is for you! Ryan is a Dad, Rare Disease Caregiver and the Founder of mejo. He lives in Bentonville, AR with his wife and 3 sons.

Healthcare was always central given Bret's 20+ years working in healthcare technology. He was often out at hospitals visiting with doctors, nurses, and administrators as part of his previous executive role at Cerner (now Oracle Cerner), a large healthcare IT company.


While his background was immensely helpful in understanding healthcare, it didn't fully prepare his family for everything they needed to know when both of his sons were impacted by sudden, acute, & severe rare diseases. Experiencing healthcare from the viewpoint of the caregiver rather than the provider or patient was eye opening. There was a ton to do and and very little guidance was given on how to really do it. There had to be a better way!

That is why he joined Ryan in his mission to deliver tools and solutions like mejo that are purpose built for caregivers so they can do what they do best-take care of their loved ones! Bret is a Dad, Rare Disease Caregiver and Co-Founder. He lives in Kansas City, KS with his wife and 3 kids.
