  • "Amber Lengacher of Purple Circle was a tremendous help to us as we worked on the arduous task to secure our cannabis license in the state of Mississippi. This was a new business for us (and for Mississippi) so we had lots of regulations to meet. Amber is very knowledgeable in the cannabis space and she guided us through the process and we even delegated some of the heavy lifting to her as our consultant. She was always on top of things and helped us stay on track to meet our projected deadline to obtain our cannabis cultivation license. Amber is very personable with a great attitude to go along with all the experience she brings to the table. Her services were reasonably priced and in my opinion some of the best money we spent on resources to get our license. Amber has many talents and I highly recommend her and her company for all your cannabis consulting needs regardless of which phase you are in and which state you need assistance. We were very fortunate to work with Amber, we got our MS license, and we will definitely use her again as our needs evolve!”

    “It is my pleasure to work with Amber for the licensing process. She is obviously very well-versed in the business and went above and beyond to get everything finished in a very tight timeline. Her communication throughout the process and ability to connect me with other professionals in the industry and have a prompt return to meet deadlines was amazing! Thanks so much for everything Amber, I have so much peace knowing that I’ve given my business the best possible shot at obtaining a license, it’s a privilege to work with you!”
