Dr. Amy Steffe Lohmann

With deep sorrow, we share the news of the passing of our cherished co-chair, Dr. Amy Steffe Lohmann. Amy's strength, resilience, and boundless commitment to the fight against metastatic breast cancer have left an enduring impact on all of us.

Though she may have left us physically, her spirit will forever live on in the heart of the MetGala SCV. As we gather on September 9th, 2023, we will present a special tribute in honor of Amy's extraordinary contributions. This tribute will not only celebrate her remarkable journey but will also continue her legacy of raising awareness and funds for metastatic breast cancer research.
As we pay homage to Amy, we also invite you to support her two incredible children by contributing to their GoFundMe campaign. Your kindness will help secure their future and ensure that Amy's love continues to guide them.
