Subject:  Request to Attend the 2018 National Rx Drug Abuse & Heroin Summit
Dear [Decision Maker Name],
The National Rx Drug Abuse & Heroin Summit (Rx Summit) takes place from April 2-5, 2018 at the Hyatt Regency in Atlanta.  The Rx Summit is the largest national collaboration of professionals from local, state, and federal agencies, business, academia, treatment providers, and allied communities impacted by prescription drug abuse and heroin use. It is the event for professionals working to address this public health emergency.
I would like to request approval to attend this conference, as I believe it will not only keep me up to date on the latest research, case studies, and methodologies in fighting this epidemic, but also give me practical, “put-into-action” takeaways that I can then share with my colleagues.
If I attend I will have the opportunity to:
  • Earn continuing education credits
  • Learn from a diverse curriculum that includes hot-topic areas.
  • Re-energize myself professionally through networking.
  • Stay ahead of emerging topics that reflect today’s headlines.
  • And so much more.
PLUS, the conference registration fee includes coffee breaks and lunches.
The approximate investment for my attendance is as follows:  
Travel costs
Accommodation (3 nights at $148/night*)
Dinners (3 days at $25)
Pass for 3 days
Total cost to attend:
*Rx Summit has this specially negotiated hotel rates for attendees. 
**$745 is Non-profit, Clinician, Government, Academic Rate and $1095 is the corporate rate.
When I return from the Rx Summit, I will compile a short presentation covering speakers’ presentation notes, useful vendor product information, new contacts made, and a proposal for implementing new ideas that will benefit our team. I will also make any conference materials available to my colleagues.
I thank you for your consideration.
