About Mark Sellers
At my core, I am a career salesperson. I founded Breakthrough Sales Performance in 1998 after working twelve years in sales and sales management for healthcare companies. I am the author of two books on sales. As a small business owner, I know the pressure of hitting quota every year.


Blindspots in SalesTM throws out one-size-fits-all sales training that jeopardizes a sales leader’s credibility from two sources - her salespeople and her supervisor.
I created Blindspots in SalesTM after encountering my own blindspots that hindered progress in my personal and professional life, and then discovering “the better version of myself.” I am wildly more successful after this discovery than before.
I believe that this program, combined with fundamental sales processes and tools, offers breakthrough gains in sales effectiveness for every member of your sales team - because I’ve seen the results.
When you’re ready to take the next step, contact me. I look forward to learning about you and your sales team, the challenges you need to overcome and discussing how Blindspots in SalesTM can help.
To Your Success,
Mark Sellers
