Acknowledgments
We would like to thank the many dedicated physicians, researchers, and other clinicians who have contributed a vast amount of medical documentation regarding the devastating effects of vitamin B12 deficiency in children and adults.
We are grateful to the Groovers, the Ryans, and other families who recognized the importance of sharing their stories about their childrens B12-deficiency-acquired injuries in order to educate others. Special thanks go to Tracey and Damian Witty in the United Kingdom, who teamed up with www.B12Awareness.org to educate more countries about the dangers of B12 deficiencythere is power in numbers.
We are truly blessed to have the opportunity to work with writer, producer, and film director Elissa Leonard, who shares our passion and joined our lifelong quest to raise public awareness and expose poor health-care practices through her movie Sally Pacholok.
A big thank you to Chris Kelley, president of Polestar Communications, who taught me the fundamentals of giving a great interview and writing pitches. His continued support, advice, and friendship are priceless. Thanks also to Ron Beckenfeld, Matthew Supkoff, Steve Downs, Greg Faull, and the rest of the team at Superior Source Vitamins for their past and continuing efforts on behalf of B12 awareness and educating the public. And finally a private thanks to my dear friends Tracy Weick, Karen ODonnell, and Dr. Richard Nimbachlife would not be the same without your kinship, laughter, and listening ears.
