Dr. Osborn has authored two books, beginning with the Bioidentical Hormone Handbook in 2012. Within 2 years, the book had been published in a second edition and reprinted due to overwhelming popularity. Upon selling out of the second printing, Dr. Holdren revisited the book and teamed up with Dr. Linda Jeffrey. Together they expanded the contents and updated sections from expert contributors for a new revised and retitled book, Dr. Deanna’s Healing Handbook, in 2013.
