About Us


It is our mission to empower those who perform, teach, and manage blood collection procedures for clinical testing to do so with professionalism, integrity, precision and compliance.


Since 1998, the Center for Phlebotomy Education, Inc. has been having a global impact on how blood samples are drawn and processed for clinical laboratory testing. As a trusted leader in the healthcare industry, tens of thousands of healthcare professionals and facilities worldwide have attended our conference presentations, invited us to conduct onsite training, implemented our educational materials, subscribed to our newsletters, and interacted with us through our web site.

Our expertise has been sought by clinical laboratories, healthcare facilities, academic institutions, government agencies, product manufacturers, and dedicated healthcare professionals around the world.

Healthcare professionals and educators around the world have relied on us for accurate information on blood sample collection and processing (preanalytical) procedures since 1997. Through our videos, newsletters, books, posters, downloads, continuing education exercises, conference presentations, in-services, and more, we’ve been teaching proper phlebotomy technique based on the most current CLSI standards and OSHA guidelines.

We are not a certification agency, but we support comprehensive phlebotomy training and certification for all who have blood sample collection responsibilities.
