Speaker's Bureau
Sandhill Scientific recognizes the importance of education for health care professionals in order to provide accurate data for their patients undergoing esophageal or anorectal studies and to better understand their role in their patient's care. We therefore have assembled a team of experts in Reflux Testing as well as Esophageal and Anorectal Manometry to form the Sandhill Scientific Speaker's Bureau, providing a broad base of clinical education in their areas of expertise. Please contact us if you are interested in inviting any of the members of our Speaker's Bureau to participate in your upcoming events.

He has authored over 500 publications including the major text in this field, The Esophagus, 4th edition, 2004.
