Lauren Nachstein, Chair


Lauren Nachstein is the Head of Audience Insights and Research at RICS, a global professional body promoting and enforcing the highest international standards in the valuation, management and development of land, real estate, construction and infrastructure. She got involved with Lung Force back in June 2018, just a few weeks after her husband Andrew was diagnosed with stage 4 metastatic lung cancer at the age of 35. Feeling lost and hopeless about Andrew’s diagnosis, she joined Lung Force to find hope, to help find a cure for her husband, and also as a way to rally the troops and cheer him on through his battle. Sadly, despite Andrew’s fierce determination to live, he passed away on October 16, 2019, just 17 months after his diagnosis. She stays involved in Lung Force to raise funds in her husband’s memory in hopes she can help find a cure for someone else so that no other family has to face the unimaginable pain her family experiences on a daily basis. She continues to walk and raise funds and awareness because she knows how important education and early detection are to beating this disease. She also hopes for the advancements of treatments so that they result in fewer side effects, something her husband faced on a daily basis. Most importantly though, she stays involved in hopes that she is making Andrew proud of what she is accomplishing in his name.

In addition to her work at RICS and involvement with Lung Force, Lauren is also an assistant Girl Scout troop leader for an energetic group of Brownies.

Mariann Casagrande


October 23, 20201 marked 6 years since Mariann’s life changing diagnosis of Advanced Non-Small Cell Lung Cancer. She joined the LUNG FORCE Walk Westchester in 2016 and is proud to be a voice for all of us on this journey. She is positive, encouraged and hopeful that increased awareness and funding will continue to keep giving options in treatment and care. Mariann was honoured to be part of LUNG FORCE Advocacy Day in 2020. It was a virtual experience that had a powerful impact on the representatives from our states for increased funding and healthcare protections.

Together with family and friends, Mariann will continue to fight this fight for all!!

Tracey Garzione


Tracey joined LUNG FORCE in January 2016 after caring for her mom, Judi who died within 6 months of diagnosis on October 14, 2015 from a rare form of lung cancer - Large Cell Neuroendocrine Carcinoma.

She devoted her career life to the aviation industry, where she control situations or "fix" them. When cancer struck her family, she found herself in uncharted waters - not having any control over or being able to fix this horrible disease.

She found LUNG FORCE while researching the cancer her mom had and decided to be a part of this important initiative to help others but especially to keep her memory alive. Every year since inception, her team 4u JuJu walks -- for her and for everyone encumbered by lung disease -- to hopefully find a cure one day.

KatieLynn Mulligan


KatieLynn Mulligan is the Marketing Coordinator for Martin Clearwater & Bell LLP, a defense law firm in Manhattan. She became involved with the American Lung Association after she lost her Mom, Patricia, in October 2017 to lung cancer.

To keep her memory alive, the Mulligan family hosts an annual golf outing in her name through Katie’s Dad’s business - Mulligan’s Fireside Pub, and donates all proceeds to The American Lung Association.

When Katie was approached to join the leadership committee for LUNG FORCE Westchester, she did not have to think twice about joining. To “go above & beyond” was her Mom’s famous line, and Katie intends on doing just that in memory of her and for all those who continue to fight.

Kristin Ohnmacht


Kristin Ohnmacht has been the Director of Marketing for Bilotta Kitchens for 19 years. She became involved in Lung Force as a team member on Love Your Lungs in 2018, just after her brother-in-law, Andrew Nachstein, was diagnosed with stage 4 metastatic lung cancer at the age of 35. Sadly, in 2019, Andrew lost his courageous battle against lung cancer leaving his family in incredible pain with a hole that will never be filled. In 2021, Kristin decided to join the Lung Force Westchester committee as a way to honor Andrew and support her sister, Lauren Nachstein, who was already a committee member working to promote and educate despite her own unimaginable grief.

Peggy Ohnmacht


My name is Peggy and LUNG FORCE is a particular mission for me. My mother-in- law passed away in 1992 and my mom in 1993, both from lung cancer. In 2019 we lost our son-in-law after a heroic struggle, also with lung cancer. But my story doesn't end there. My brother-in-law passed away in 2021 from pulmonary fibrosis. My brother continues to recover from one of the worst cases of Covid one could have and survive, but after 15 months he remains on oxygen and is dependent on others for help with all daily activities. He was healthy and active when he contracted Covid, likely at a yoga class. He will never be the same. Then there is me- recently diagnosed with ILD or idiopathic lung disease. Not sure what my future holds, but I am counting on science to find treatment.

I am counting on lung research to find treatment and cures, and will do my part in making it happen.
