October 1, 2016

To my dear patients, referring physicians and practitioners, and my wonderful staff,

It is with a bittersweet feeling and an overwhelming sense of gratitude that I have been blessed with 44 years of caring for people who have experienced quality of life compromises because of symptoms addressed by this specialty of allergy, asthma and immunology.

This career journey has led me through so many wonderful experiences whether it has been writing chapters published in textbooks, clinical research,a creating a foundation for the poor to educate those especially with asthma, serving on national committee boards, but most especially by interacting
with each of you one by one.  It always was my dream to be a part of a process that diminishes suffering in the world no matter through what instrument.   I have been blessed and more fortunate than I could have imagined to have found so much of this through the practice of medicine.

No person owes more than I to those who have accompanied me along this journey.  They have assisted me, groomed me, have smiled with me, have cried with me, and have laughed with me.  I have learned so much about life from all of you: my mentors, my staff, my peers, and especially from my patients.

Now it is time for me to step aside for the next generation of caregivers, leading me to announce my retirement as of midnight, December 31, 2016.  I leave behind a wonderful history and an outstanding staff to continue the mission of Allergy & Asthma Care and Prevention Center, P LLC, led by the very capable and sensitive leadership of my partner, Dr. Lora Stewart.  I am convinced she will guide this practice well beyond expectations.

I shall miss dearly my relationships with every one of you with whom I have had professional contact and beyond.  You have been my friends and represent the grace that has been bestowed upon me on this journey.

My wish for all of you is good health, a peaceful and safe world, and much love as we all quietly age.

Thank you all for being a part of my life.

Your retiring servant,

Sanford (Sandy) E. Avner, M.D.
