Fred was a highly respected teacher and colleague. I am so sad to hear of this news, as the world has lost an incredibly compassionate, dedicated, and intelligent man. I remember many clinical lessons he taught me, even twenty years later. And I remember how thoroughly he helped me to prepare for my oral board exam in 1999. Back in those days, there was a 60% fail rate at the first attempt for the psychiatry boards oral exam. Fred helped me to prepare so that I was one of the fortunate few who passed on the first try.
Thank you, Fred, for all that you did for so many patients. Your research will continue to light the way for future generations of physicians to continue healing those who suffer.

In addition to all his other accomplishments Frederick was an accomplished genealogist. He spent his adult life capturing his German lineages including collateral lines - including mine.
For me and other Newbrand family members Frederick answered all requests for information he received. He always answered with much data and documentation - willingly and with full exposition.
For the Newbrand family he was a living Ancestry, 23 & Me and Family Search engine!
I first communicated with him by mail going back many years but then had to opportunity to meet him in person and speak by phone after moving to Raleigh/Durham in 2011.
He was as gracious in person as he was by mail. He will be missed....."Ruhe in Frieden, Cousin....

Dr. Cassidy was a wonderful person. I came to know him and worked with him closely when he was president of the Medical Staff at JUH and later CRH. He had a high standard and required it of himself and others. I have since retired but I know his expertise and kindness will be missed. He was a wonderful, caring person.

I remember Fred from my days at John Umstead hospital from 80s till ‘95 when I left JUH to work at Nash Health System. I will always remember Fred’s kindness and genuine concern for patients and collegiality . I used to call Fred from other hospitals I had worked - like Dorothea Dix Hospital & Johnston Health to refer a patient for consideration for ECT,Fred was so very receptive ,kind & helpful to work out the logistics . I admired his sincerity & concern.
May Your Soul Rest In Peace, Fred.!
May God give comfort, courage and peace to your family🙏🏽

I came to know Dr Cassidy in 2008 when I came to work at Central Regional Hospital. He truly cared about his patients and his work. Asking doctors to do peer reviews for insurance is never a favorite task, but he was always willing to go to bat for our patients. He also cared about is coworkers. CRH and the world lost an amazing person and terrific doctor.

I was a resident with Fred in the same class in psychiatry at Duke. I didn't have many close friends in the class, but Fred was one of them. He was a good friend, kind and generous, willing to help out at a moment's notice. He was also a wonderful clinician, willing to go above and beyond for his patients. I feel blessed to have known him, and I will be praying for his family during this difficult time of grief and loss.

I was heartbroken to first hear about his illness and then his untimely death. I met Fred in 1988 when we started the psychiatric residency program together. After graduation, we both joined John Umstead Hospital and worked together on many units and also the ECT service. I left that position after six years but saw him several times in recent years when I went to the hospital to do forensic evaluations. He always greeted me with a big smile and a big hug, before we reminisced about the past. He was a wonderful person and a very competent and compassionate physician. He had a quiet demeanor, a big heart, a great sense of humor and an easy laugh. He devoted his professional life to treating people who had severe mental illness and served them with great competence, compassion and grace. My heartfelt condolences to his family for their immense loss. We have lost a great colleague too.

I was privileged to know Fred from his residency forward as his social worker, as his yard man for a while, and as his friend. He was a truly accomplished man. However, I think I will most remember and miss his big heart and kindness, which he did not usually like for others to see……To illustrate; we had a patient who had financial distress and had placed great hopes on an upcoming job interview. She was, quite clearly, unfairly committed to our facility over a weekend and was distraught at losing her only opportunity for work. It truly just a circumstance that was not fair to her. Fred directed me to call a cab for her, took money from his own wallet to pay the fare, and swore me to secrecy. That’s how he rolled. Quietly. Effectively solving problems. With great compassion and personal generosity. And always, humbly preferring to stay in the shadows. We are going to miss him.

Dr. Cassidy will be truly missed by friends and colleagues. I had the privilege of working with him at John Umstead and Central Regional Hospital. We shared much laughter over the years. I admired the way Fred lived his life and the light he brought to those who met him. I am sorry for the loss!
