Dr. Grattan’s Retirement Letter
Dear Valued Patient:
After a career of over 50 years as a physician, I have decided to retire from active clinical practice effective January 31, 2026. It has been an honor and privilege to be able to guide you through your medical needs over the years. I am very grateful to all of you as you have added great meaning and purpose to my life.
I encourage you to continue to be seen at Cardiologists of Lubbock with one of my extremely capable partners. We have recently been joined by our newest partner, Dr. Nestor Mercado. He is joining us after practicing for over 1 O years as an interventional cardiologist. He recently moved from Oregon to Lubbock with his family and we welcome them to our community. He has had excellent education and training and is fully capable in all aspects of cardiology. He is a highly compassionate physician with outstanding clinical skills. I highly recommend Dr. Mercado.
The following is a list of my other current partners who are still accepting new patients:
- Dr. Mounir Barno
- Dr. Walter Brogan
- Dr. Alan Sharif
All records will be retained confidentially here at Cardiologists of Lubbock. If you choose to be seen elsewhere, you will need to complete a medical records request and records will be provided to a physician of your choice.
As a young physician, I dreamed of a career that would be fulfilling and impactful. As I enter my retirement, I thank you for making this youthful goal a reality.
Wishing you the best of health,
– James Grattan, M.D.
For current patients of Dr. Grattan, Dr. Mercado will be available.
