I have been a patient of Dr. Sullivan for many years and today found out of his demise. He treated me for 3 forms of cancer and I am now in remission. Your husband and my friend has saved my life. Truly a dedicated physician and a fantastic human being. He wanted me to speak french with you.
May the Lord bless you and your family.
Il est avec le Dieu.

So sorry to hear of Dr. Sullivan's passing. Words are so inadequate to express what a wonderful, caring person he was, and what he meant to my family and this community. Our thoughts and prayers are with the Sullivan family at this time.

Jean and family, I was shocked to hear about Peter! I always enjoyed his humor and his passion for collecting art. He was so proud of his family and all they accomplished. Please know that I am here to help. Consider me your Janet S. replacement.

I am so sorry to hear of Dr. Sullivan's passing. I called on his office with Amgen for the past 4 years, and I enjoyed his entertaining stories and his quick wit. He was so proud of all of his family. The last time I saw him, he made a reference to hoping to be able to age with dignity and he certainly accomplished that, along with so many other things, including seeing the Cancer Center come to fruition. I will miss him and I wish you all peace and happy memories during this very sad time.
