The Mast Cell Disease Society Welcomes Three New Board Members


The Mast Cell Disease Society (TMS) is pleased to announce the election of three outstanding individuals to its Board of Directors: Bonnie Nasar, Brian Ahrens, and Jennifer Lockhart. Each brings unique expertise and dedication to advancing our mission of supporting patients, families, and caregivers affected by mast cell diseases.



The Board of Directors plays a vital role in guiding TMS’s programs, advocacy, and vision for the future. With the addition of these new members, our organization is well-positioned to strengthen its impact and continue driving progress in research, education, and patient support.

“Prior to their election to the Board, all three of our new directors had already made significant contributions to TMS.  There is no question that their leadership and perspectives will be invaluable as TMS continues to grow and serve the mast cell community,” said Judith Emmel, Chair of the TMS Board of Directors.

We are excited to welcome our new board members and look forward to working together to expand resources, build awareness, and champion progress for all those living with mast cell diseases.


Please join us in congratulating and welcoming Bonnie, Brian, and Jennifer to the TMS Board of Directors!
