Ryan Clark, PAST Board Member

Ryan Clark

Prior to starting PeopleShare, Ryan’s experience included over 20 years in the staffing industry and extensive sales and sales management experience in the pharmaceutical industry. During his 7 years at PDI, the world’s largest contract sales organization supporting the pharmaceutical industry, Ryan continually rose through the ranks. Beginning his career as a sales representative, Ryan was promoted several times and was eventually made region director of the northeast sales organization. At PDI, he was continually a top performer and was recognized in the company’s circle of excellence, which was awarded to only the top 2 percent of company management. In early 2003, Ryan was hired by a major Philadelphia-based staffing company to turn around their unprofitable Philadelphia market. Within 8 months, Ryan led a team that increased revenue from $16,800/week in June to $63,000/week in December, for a 275% increase in revenue. Within 3 months Ryan turned the unprofitable office into one of the most profitable offices in the company and was consistently recognized as one of the top five managers in the company. Ryan’s experience, talent, and drive bring the depth to the PeopleShare management team needed for long-term growth.

Federation of State Medical Boards

The AAOS recommends the following tools, which have been shown to significantly reduce medication errors:

  • computerized physician order entry
  • computerized decision support systems
  • computerized monitoring of adverse drug events
  • pharmacist-assisted rounds
  • high-risk drug protocols

Overdose deaths are “just the tip of the iceberg”: that for every death there are many more hospital treatment admissions, emergency room visits, people who abuse or are dependent on prescription drugs and nonmedical users.
