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.

Wait - What? Who is sending their kids out this year to touch doorbell buttons and doors and hands of countless neighbors? Super spreader day for kids? And…. don’t get me f-ing started on excess sugar and child diabetes. #cancelhalloween

Thank you Kara. It’s standard operating procedure for the full grown smug, arrogant Hitler youth. See also @ValuetainmentTV @patrickbetdavid interview with yet another Facebook whistleblower.
Kara Swisher @karaswisher
There it is @profgalloway — their attempt to paint the whistleblower @FrancesHaugen as a nobody, a know nothing. Well, if I have watched the C-suite in action for 15 years persistently prevaricating and the smug arrogance of it still leaves me breathless. Defense sure, but ugh.

“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.”
