Learn MoreThis experience has been incredible. I have been studying and practicing herbalism for 15 years and this program stands out among so many I’ve done. I am so impressed and grateful. I’ve been able to heal some things I’ve dealt with for years through what I’ve learned here. Your whole team is just awesome. This program has definitely not been easy! And I love that – the challenge is where growth takes place. Wow has it flown by. I’m soaking up these last few months of class. Thank you so much.
