BottleKeeper®

Co-founder/CEO (acquired)

I was a partner in this medical tech company that grew rapidly as a result of understanding how to leverage federal laws from the 1970s that enforced private health insurance reimbursement for covered out-of-network orthopedic procedures. Although I did exit my position in this company, the experience (combined with the prior medical device company not included) taught me countless hard earned lessons, the vast majority of which were about how NOT to build a team and company. Yep, loads of stories from this one :)
