I personally do not care for this dispensary, I feel it's overpriced from where I usually go and the Js seem to also be lighter than my other location. The staff is great and friendly but not happy with product

Amanda did an amazing job educating myself and my wife on the process. We are new to the state and come from an illegal state. Her knowledge and overall energy was among the best I have ever encountered in any customer service experience. GIVE THAT GIRL A RAISE!

Needed to get a new chillum. They had so many choices with great prices. I couldn't decide on just one. I got one of each. That will come in handy the next time one gets broken from one reason or another. Sean was wonderful and he said, "Oh yes. I remember that order." Made me feel kind of important. Thank you!
