Twila was an absolute hoot to work with. Super knowledgeable about all things bud so she definitely made some stellar recommendations. Actually the whole staff including your boy at the front are top tier. Gramz being 24 hours with such a wide variety and selection just made the experience that much better. I still wanna recommend that you get a disco ball and party lights in there 🤣🙏🏼

Out of all the dispensariesI have been to this one has been my favorite by far. The Staff is always very friendly, knowledgeable, and helpful. Every time I have been here they have always made me feel welcome and and have never made me feel rushed. I highly recommended this place it's a great experience every time. GREAT SERVICE, GREAT SELECTION, GREAT QUALITY, AND GREAT PRICES.

Jaxom was absolutely awesome! Very knowledgeable, passionate about the product, and even more passionate about making sure you get exactly what you are looking for. He took the time to explain things in detail and ultimately helped us select some products we haven’t tried before! Awesome experience! Will definitely be visiting him again soon!

Kelly was amazing and super patient with us while we were bulk shopping deli and wanted to see quite a few. I loved that when I told her I wanted something that stunk like a dirty foot or armpit, she knew what to show me! Other places just show me whatever is first to grab. I liked the banter and vibes from reception as well, wish I would have caught her name!
