I am a Certified Aromatherapist. Knowing how to make a blend using tools that I learned while in college has helped me to work with clients safely yet, effectively. I will do custom blends along with selling my current blends. If someone would like a different sized bottle other than what I sell, that can be done. (some restrictions may apply). I will answer any question and will reply within 24 hours. If there is research involved with answering a question, I will certainly let you know that and follow up with an answer.
