Carissima maria,,,

Heartfelt condolences,,,UN FORTE ABBRACCIO,  Phyllis and Claudio🙏

John was a fellow one year ahead of me at Northwestern.  He was always asking the new fellows how they were doing and what help/advice they needed.  His positive attitude was invaluable in the fellows room.  I was so saddened to hear about his passing.  May his memory be a blessing. 

I worked with John at Incyte and was heartbroken to hear of his passing. He was not only our GVHD expert but a genuinely kind and thoughtful colleague who always made time to stop by and say hello when visiting the Chadds Ford, PA office. My heartfelt sympathy to Maria and his family. May his memory be a blessing to all who knew him.  

John and I worked together together at Northwestern years ago as  he was often a fellow in our clinic. He was a kind man with an infectious smile. That is what I will always remember about John.  You and your children are in my thoughts. 

John and I were fellows together, and I’m just heartbroken that he’s left our world. He was always smiling, and always willing to lend an ear and share a laugh. I send all my love to his beautiful family. 

My heartfelt condolences to John's family. I first met John when we worked together at Northwestern Medicine. John was a critical member of our team working on achieving kidney transplant tolerance through combined kidney and stem cell transplantation.  His support and enthusiasm for this work was inspiring.  He was an outstanding scientist and amazing clinician - his patients absolutely loved him.  After leaving NM and moving to Incyte, we continued to talk and meet to discuss ways of improving lives of patients through novel therapies.  He was one of the most genuine, funny, and down to earth people I have had the pleasure of knowing.  May his memory be a blessing...

I am so very sorry for your families loss.  I send my deepest condolences to all of you.  

This is terribly sad news to hear today... and shocking. I enjoyed getting to know John and his family over the past 6-8 yrs or so. John would always stop by my gallery on his walk home from dropping his kids off at school and we would chat. Our love of Detroit/Grosse Pointe, the Lions, mutual friends and contacts in common. He loved the arts and championed an underprivileged kids photography group. Like many have said here, he was a kind man with a smile on his face. He was considerate, compassionate and smart. 

I will miss talking to him and want to offer my help if the family needs anything.

I had the privilege of working with John at Incyte. I looked up to John. He was a brilliant, kind soul both inquisitive and hard-working. He relentlessly advocated on behalf of researchers and patients alike, helping to drive research to improve patient’s lives. His impact will be felt for years and decades to come. I truly feel that knowing him and working with him was a privilege and want to express my deepest condolences to his family. He is truly missed.

My deepest condolences for your terrible loss.  Please know that we at Lincoln hold you all in our hearts.

I knew John from his clinical fellowship in Hem-Onc  at Northwestern.   At some point he also worked in my laboratory doing medical research and I got to know him well.  He was one of the nicest, most generous, most compassionate, people I have ever met.  A remarkable doctor and a great human being.  Please accept my sincere condolences.

I had the honor of working alongside John at Incyte for the past six years. His smile was contagious, and his quick wit and sense of humor always lifted the spirits of those around him. John’s warmth, kindness, and compassion touched so many lives. His loss leaves a deep void in our hearts, and he will be remembered with great affection. My deepest sympathy for his family.

John and I trained together in fellowship and then worked as co-faculty at the University of Illinois. John was one of the most gregarious people I knew...he loved being around people and cared deeply for his friends, colleagues and above all his patients.  I recall rounding on the inpatient service and one of his patients who was having a rough time sleeping on the hospital bed was beaming ear to ear one morning...when asked why, she confided that Dr Galvin had bought her a mattress topper. That was classic John, getting the job done without any fuss. John was fascinated by immunology and committed his career to trying to improve transplant outcomes, but I think his first love was health disparities. He introduced me to many of his research colleagues in this field-many of whom I now work with because of him.  There are so many memories...  commiserating failed experiments in the lab, fellowship dinners with our families, navigating faculty life at a new institution, and sharing his love for photography, including the Early Exposures program he established as a medical student to empower Chicago youth through creative expression.  May his memories be a source of strength and inspiration for Maria and their family. He leaves a void in our lives, but I feel privileged to have known and learned from him.

I first met John as a learner in fellowship around 11 years ago at Northwestern. I came in with somewhat of an interest in transplant but John played a big role in my decision to actually pursue this professionally. I spent my third year in his clinic and it was so fun having a shared enthusiasm for transplant with him and just really enjoyable being able to hang out with him. He also helped me craft a transplant focused curriculum that last year and I truly appreciate his sincere effort to help me with that. I’m grateful he remained in touch as a friend and colleague the years that followed. I always looked forward to meeting up with John, I will miss him dearly. May there be patience alongside God in his passing. My sincere sympathies to you Maria and your children.

I had the privilege of working with John at Incyte as part of the US Medical Affairs and Lymphoma Team. He wasn’t just a colleague — he was a mentor, a confidant, and a true friend. John had this incredible way of making time for people, no matter how busy he was. Whether it was a quick call to talk through a work challenge or a personal situation, he always listened with patience, empathy, and genuine care.

When my stepson was diagnosed with cancer, John was one of the first people I turned to. His guidance and kindness during that difficult time meant more to me than I can ever put into words. He had such a rare combination of wisdom, warmth, and compassion — qualities that made everyone around him better.

John’s passing has left a tremendous void in our hearts and within the Incyte family. I miss his steady presence, his sense of humor, and his unwavering support every single day. I’m so grateful to have known him, learned from him, and shared in his friendship. His impact continues to live on in all of us who were lucky enough to know him.
