Mark has a great story and is to his core a wonderful and kind person. However, don't take my word alone...Look at his reviews on Yelp such as these:

"...Theory Coffee exudes hard work and dedication, love for their product and their customers, and excellence in their coffee. Since his days at Local and then Indy, the owner, Mark, has work constantly and consistently to create what I think is our city's best coffee. What other coffee place makes their own almond milk? And, like other high end coffee purveyors, Theory makes their own sauces for use in flavored beverages.This craftsmanship and unwavering devotion to providing the customer with quality of the highest caliber, places Theory in rare company..." - Ahsan C.


"This is my first experience outside of commercial coffee chains, and I am thrilled I stepped outside of my comfort zone! Their coffee is fresh, bold, and flavorful! I tried their cappuccino and it was not only distinctly delicious, but creamy and inviting on this chilly morning! They have picnic tables surrounding their mobile coffee studio, which is perfect for sitting outside and enjoying a beautiful day like today! The 2 coffee artists running the establishment were very kind, and helpful. I will most definitely be returning!" - Kiley G.

We are excited to announce that Theory Coffee is G&M Approved and we look forward to years of enjoying sip after savory sip...
