Dear Patient’s,
It is with a very heavy heart that we regret to inform you that Dr. Richard Brasington passed away on Sunday April 30th. Dr. Brasington was a very dedicated, physician who had a profound impact on Rheumatology. He was a wonderful clinician, mentor, educator, and champion of patient care. He will be greatly missed.

Unfortunately, we will not be able to continue to care for his patients and we are advising you to call your insurance or primary care for referrals to a new Rheumatologist. We will do our best to facilitate the transfer of care to another healthcare provider. We will make copies of your medical records available to the Rheumatologist you designate once a signed release form is received. We will also be available to discuss your care with the Rheumatologist. Additionally, we will provide prescription refills for at least 90 days.

If you have questions about this transition, please contact our office at 314-567-5100 or visit our website at for information. Our office staff will be able to assist you and answer any of your questions or concerns.
