Immediate Former President

Debra Greenspan


My name is Deb Greenspan and I have been a member of ENS since 2003 to the best of my recollection and no I don’t belong to AA. I have been an endocrine nurse practitioner since 1999 doing general endocrinology at the VA Tennessee Valley Healthcare Facility (VATVHS) in Nashville, Tennessee collaborating with my Vanderbilt Physician colleagues as well as the other 175 nurse practitioners on the staff of VATVHS. I have served on the ENS board for the past 18 months working on the Research Committee. Most recently I collaborated with Andrew Dwyer to present at ENDO 2021 a program on the ENS Position Statement on Transgender Care.

My background is lengthy because I am old or should I say seasoned; so I’ll give you the short version. I was an ICU nurse from 1977-1994. I started working in AIDS/HIV care in 1987 in New Orleans and continued that work until 1996 albeit in Nashville from 1994-1996. I transitioned to the VA in 1996 and worked as a Women’s Primary Care Provider at VATVHS, Nashville until 1999 when I joined the Endocrine Service as noted above.

I am not currently engaged in formal research but enjoy the process greatly. I presented a poster at ENS in 2013 on a patient of mine with an inoperable goiter. I have attended annual meetings intermittently over the past 18 years but now that I have retired from the VA, I look forward to serving ENS more fully. I would be honored to serve ENS as President-Elect. I have much to learn from current leadership and hope that in the post COVID era I can help ENS to thrive and grow so that we can better serve the Endocrine Nurse from LPN to DNP.

Laura Cheng


Laura is a dedicated and compassionate nurse with a personal connection to the field of endocrinology. She was diagnosed with Acromegaly in 2012 at age 22. After receiving exceptional care from nurses following surgical removal of a pituitary tumor causing her elevated growth hormone levels, she was inspired to pursue nursing as a career. Her personal experience with Acromegaly provides a unique perspective from the viewpoint of a fellow patient and nurse. Her aspiration is to provide support and encouragement to patients throughout their healthcare journey.

She completed her Bachelor's of Science in Nursing at the University of North Carolina at Greensboro and her Master’s of Science in Nursing at Duke University School of Nursing in their Family Nurse Practitioner program. She also completed the Endocrine Certificate Program at Duke in order to advance her skills and knowledge surrounding complex endocrine disorders. Her primary nursing experience consists of work in an outpatient adult endocrinology clinic for over 5 years. She also has a passion for weight managment and bariatrics.

She maintains the belief that her experience with Acromegaly has brought many positive aspects to her life and was also the guiding light towards a fulfilling career path.
