NASTH and HTRS Planning to Merge

NASTH and HTRS Planning to Merge


Dear NASTH Members,


I am reaching out with exciting news about the future of NASTH. After several years of successful collaboration on joint professional meetings, and a year of targeted planning, the NASTH and the Hemostasis and Thrombosis Research Society (HTRS) have enthusiastically agreed to merge our societies. We believe that this merger provides significant benefits for the memberships of both societies, and to the field as a whole.

The HTRS mission is very much aligned with ours, with a focus on professional education and workforce development. They have a membership of over 600 (including a number of NASTH members), and a 25-year track record of programming and services that support this field. More information at www.htrs.org.

Combining these two societies accomplishes several important things.


  • The combined HTRS/NASTH membership represents the full spectrum of clinical, basic science, and translational science professionals in hemostasis and thrombosis. Our mission and programs will be strengthened by combining forces with HTRS.

  • Additional synergies include lower administrative costs, fewer competing events for members to attend, and more focused education and networking opportunities to advance research in our field.

How will this affect your membership?
Central to this merger is bringing together our respective memberships.


  • NASTH members who are already HTRS members will automatically be members of the combined organization, and need take no action. Your HTRS membership will continue under its current terms.

  • All other non-industry NASTH members of record as of April 1, 2019 will be given instructions to easily transfer your membership during a window of mid-May to July 1, 2019. These NASTH members will receive one year of membership free of charge in the new combined society. Details on this process to follow.

  • NASTH industry members will receive separate instructions shortly.


Key elements of the merger:


  • Name/Organization: For a variety of reasons, we will combine under the HTRS name and existing nonprofit legal entity.

  • Governance: Our two boards will be combined, and there will be joint representation on working committees.

  • Programs: All current programs for both organizations will continue under the auspices of the merged organization.

  • The mission of HTRS currently is very close to ours. The mission statement for the new combined society will be:


The Hemostasis and Thrombosis Research Society, Inc. (HTRS) is the leading North American professional society dedicated to research, mentoring, workforce development, and continuing medical education for physicians, investigators, and all health care professionals interested in advancing care for people with hemostatic and thrombotic disorders.


I would like to acknowledge and thank the boards of both societies for the thoughtful consideration given to this process, and in particular recognize the hard work over the past year of the HTRS and NASTH staff, and my colleagues on the joint HTRS/NASTH Merger Planning Committee.


  • Rebecca Kruse-Jarres, MD, MPH – HTRS President
  • Wolfgang Bergmeier, PhD – NASTH Director
  • Shannon Carpenter, MD – HTRS Vice President/President Elect
  • Barbara Furie, PhD – NASTH Director
  • Bryce Kerlin, MD – HTRS Director
  • Jeffrey Weitz, MD, FRCP(C), FACP – NASTH Director

This is an exciting juncture for our society. We are confident that this merger is an important milestone that sets the stage for more growth and opportunity for our members and for the thrombosis and hemostasis community at large. We look forward to sharing more details in the coming weeks.

Rodney Camire
Chair of the Board, NASTH
