My Credo: To leave people and companies better than I found them.

See how you, your team and your business can be better off with the help of The Biz Doc.


Who Is The Biz Doc?

At my core, I am a teacher, mentor and  business driver.  I am also an author, investor, board member and adjunct professor.  I have also been a founder wearing multiple hats.  Along the way, some very cool colleagues dubbed me the “Biz Doctor” which became “The Biz-Doc” and the nickname stuck.


Case Studies

I have been blessed to have been part of some excellent businesses that did well and some that didn’t achieve what people (especially the investors – and I was among them) envisioned.  In every outcome there is a lesson.  In sharing these stories in understandable ways, Case Studies with the Biz Doc was born.  Building this library of learning is a passion of mine.  And, thanks to the power and reach of digital media, I can teach and mentor anywhere in the world.

Appreciate Mayor @FrancisSuarez of Miami for helping a not-so-small city attract tech start-ups and innovators. Yes, he also is a crypto proponent and we'll see how that market fares. But he is all about attracting entrepreneurs and I salute that 100000000000%.

Warning to NFC:
Aaron Rodgers has a strong running game and Dak Prescott isn’t back for 8 weeks and Trey Lance is out. Arizona seems very good, not great. Does Brady have enough?

Yes! @DiMartinoBooth repeats what no one wants to hear - In the USA year-by-year the participation rate in the labor force is dropping. This is not due to Covid, this is a trend of laziness over the last 15 years, folks. The labor force wants to suck the govt teat and get free $.

This is dated. I’m getting a more up to date one. But just to hold over the naysayers.

“My driving passion at this point in my life is to (1) support great companies, and (2) teach, coach and mentor great people from CEOs and leaders to front line staff.”
