About Us


Previously known as Kent Homeopathic, Synergy was founded in 1986 by David Warkentin, who was passionate about homeopathy. David had a vision to distill the complex process of homeopathic case analysis into an intuitive program that would expand the knowledge base and curative abilities of homeopaths everywhere. MacRepertory and ReferenceWorks are the two iconic programs that came out of this effort and they have been indispensable and powerful tools for case analysis and effective prescription for the last 30+ years.

Most recently, Synergy has taken this innovation further by launching Synergy Homeopathic Software which is a transformation of the old programs into a state-of-the-art software that is several potencies higher.

MacRepertory is our repertorization tool. It makes it easy to analyze each case, select rubrics and check the materia medica, providing the practitioner with confidence about their prescription.

[font_style size="1em"]Referenceworks is a rich and revolutionary search and analysis system utilizing a vast library of more than 850 volumes of materia medica, provings, journals and more. You can simply search, in your patient's own words, within the extensive library to instantly discover the most likely remedies for your case.[/font_style]

At their root, MacRepertory and ReferenceWorks were created out of a vision. And as always, the vision, innovation and drive to advance homeopathy is still at the heart of what we do. Today, our patron Dr. Rajan Sankaran leads a company committed to developing this software as the homeopathic tools of the future.
