“I have known Dr. Dan for many years, and he is deeply knowledgeable about all subjects surrounding plant medicine, psychedelics, and other forms of healing with non-ordinary states of consciousness. 'A Dose of Hope' is a terrific book that helps demystify the process of MDMA-assisted therapy in a clear and compelling manner. Dr. Dan's book will become a key public education resource as legal access by prescription to MDMA-assisted therapy for PTSD is likely by early 2023.”
— Rick Doblin, Ph.D., Founder and Executive Director of MAPS
“A lot of health care practitioners throw around the word holistic, but no one I have ever met embodies this ideal like Dr. Dan Engle. Physical, mental, emotional, and spiritual wellness are all inexorably woven together into his practice. He is the perfect person to write the book about one of the most significant advancements in wellness we have ever seen in our lifetime. To understand what is possible with MDMA assisted psychotherapy, both personally and collectively, this book is a must read.”
— Aubrey Marcus, Founder of ONNIT, NYT best selling author of Own the Day
“Dr. Dan Engle is one of the most knowledgable people on the planet. Over the years I have referred him and his work to everyone from a mother that has a son struggling with Depression or Addiction to billionaires that have searched endlessly for solutions to psychological pain that they have not been able to find. He is a brilliant man who is on the new frontier of bringing relief to the pain and suffering that so many people live with.”
