Jeff Dillon


Dillon received his MBA in Marketing and Operations from Vanderbilt University Owen Graduate School of Management.

He is an established business professional with over 20 years of experience in marketing and sales management. The bulk of his career has been spent in pharmaceutical manufacturing with a focus on marketing and sales management. Dillon launched multiple new pharmaceutical brands both in the USA and internationally. But his more recent years have been spent in pharmaceutical sales management where he managed a sales team of over 100 people.

During this time, he saw a need to help men in Colorado get their sex lives back after noticing that big pharma companies were advertising their oral medications for erectile dysfunction. But the problem was that they only work in about 1/2 of guys, and even then they may not be able to tolerate the side effects. Knowing oral medications may not be an optimal solution for a large segment of the population with ED, Dillon started RMMC to help men actually get results they are looking for.
