My father was a dentist and he taught me that Ambrose Pare was the father dentistry. 
That is great.  Are you a dentist?
In the process of becoming, currently a student in dentistry college. 
Good luck to you.  I work in sales of enterprise software.
Thank you and how do you like selling enterprise software ?
I like it a lot.  I used implement it and worked long hours.  Now I sell it and a little tougher to sell high dollar software, but I enjoy it and its less hours.
That's good to hear, is the software you sell open source, which is open technology under standard commercial terms and support is valuable.
