Welcome to the College of Botanical Healing Arts

Dear Prospective Student,
We invite you to embark upon a study of the healing properties of therapeutic plants and their essential oils.  Whether you are interested in acquiring knowledge about the use of essential oils to enhance your own life, and the lives of your family and friends through the 36-hour introductory class, or are interested in obtaining the complete certification through the 456–hour program, then COBHA is for you.  The College Board of Directors and its faculty are dedicated to providing students with a quality education in the art and science of Essential Oil Therapy.
Students have many opportunities throughout the program to engage in both theoretical and experiential learning.  The academic program includes classes in chemistry, botany, anatomy and physiology, as well as classes in the more esoteric studies of energetic healing and the connection of body-mind-spirit healing.  Through experiences with plants and essential oils, students develop an understanding of the energetic, emotional and spiritual aspects of healing.  All classes are taught by highly qualified instructors.
The time to bring about a life-changing orientation in your physical, mental, and spiritual health and well-being is now!
With Warm Regards,
The COBHA Board off Directors and Staff

"I'm so impressed with the classes I'm taking and the information I now have about the science-based use of essential oils and can't wait to continue my studies of them!"

"I loved my COBHA class.  Thank you for sharing all of your wonderful knowledge!  I hope to take more classes as soon as I can.  Being a seventh grade teacher, my aromatherapy products I made after the class have been a great hit with my students, especially the boys.  They love the “Brain Blast” spritzer made of rosemary, lemon, and peppermint.  It helps to keep their attention focused."

Financial Policies

Refund Policy

Students who wish to cancel their enrollment in a class must do so in writing. The written statement must include the date of withdrawal, the reason for withdrawal and signature.

Students withdrawing from the Level II program should schedule an appointment with a school administrator.

After the first class, a student will receive a full refund, excluding the $50 nonrefundable registration fee.

After two weeks or the second class, the school reserves the right to retain the full tuition. If the student is on the payment plan the remaining balance is still due to the school on the contracted days. This protects our school from students who lack a serious interest or commitment to our program.

Financial Aid

Students may qualify for certain financial aid from outside agencies.

Students are responsible for identifying and applying for any such aid.

COBHA offers a payment arrangement which shall be approved by the administration at the time of the admission interview.

COBHA also honors grants and scholarships that are awarded from outside sources like EDD or Federal grants.

There are times when COBHA can offer partial scholarships to its students, but these circumstances are ever changing and are not guaranteed.

Student Tuition Recovery Fund

The Student Tuition Recovery Fund (STRF) was established by the California Legislature to protect any California resident who attends a private post secondary institution from suffering financial loss as a result of the school closing, failing to live up to it’s enrollment agreement, or refusing to pay a court judgment. To qualify, a student must be a permanent resident and keep copies of the enrollment agreement, receipts, etc.

Payment Plans

Payment in full for any course of study may be made at the time of registration. However, installments that run over the duration of a class can be arranged in advance through the business office, and are split up into three payments. Payment one is due Class 1, the second class 3, and the third class 5. Visa, Mastercard, Discover, and AMEX are accepted, as well as cash, check, or Paypal.
