A Message from Dr. Sunder About Your Continued Care

July 1, 2026

To All of My Valued Patients and Friends,

After more than 50 years of providing cardiac care to the communities of Antelope Valley and Kern County, the time has come for me to retire from clinical practice.

Since 1975, I have had the privilege of caring for you and your families, and it has been one of the greatest honors of my life. Thank you for placing your trust in me throughout the years. While I hope I have made a positive difference in your lives, I want you to know that you have profoundly impacted mine.

Your resilience, kindness, courage, and personal stories have taught me invaluable lessons and have made me not only a better physician but also a better person. I am deeply grateful for the relationships we have built over the years. I will always remember you with great fondness, gratitude, and appreciation.

I have taken great care in identifying a cardiologist who is exceptionally well qualified to continue your care. I have every confidence in Dr. Kanwaljit Gill, who will continue caring for you and your families. Dr. Gill has served the Antelope Valley community for the past 30 years and will be pleased to provide for all of your cardiac care needs.

I am confident that you will continue to receive the excellent care you deserve, and I encourage you to maintain your regular appointments with the practice and your new healthcare provider.

Thank you once again for allowing me the privilege of being your physician. I wish you and your families continued health, happiness, and all the very best in the years ahead.

With sincere gratitude,
Shun Sunder MD

Familiar Faces in a New Office

To help make this transition as smooth as possible, some members of my staff will be joining Dr. Gill's office. This means you may see familiar faces who know you, understand your history, and can help support continuity of care. This continuity was important to me as I planned this transition, and I am grateful that Dr. Gill has welcomed members of my team into his practice.

What You Need to Do

Transitioning your care is simple. Please call Dr. Gill's office at (661) 940-4444 to schedule your next appointment. When you call, please let them know that you are a transferring patient from Sunder Heart Institute. Dr. Gill's team will be expecting your call and will help make the process as smooth as possible.

Your Medical Records

Your medical records, including available test results, imaging reports, and treatment history, will be securely transferred to Dr. Gill's office in compliance with HIPAA requirements. You do not need to take any action for this transfer to occur.

However, you have the right to choose any physician for your continued care. If you prefer to have your records transferred to another physician of your choice, please call our office at (661) 726-3000, and we will assist you with that request.

Transition Timeline

Until August 1, 2026, I will remain available at my Lancaster office for urgent cardiac concerns. Beginning August 1, 2026, Dr. Gill's office will assume responsibility for your ongoing cardiac care. After that date, please contact Dr. Gill's office directly at (661) 940-4444 for appointments, prescription refills, and questions regarding your cardiac care.

For any cardiac emergency at any time, please call 911 or go to the nearest emergency room.

A Personal Note

Caring for you has been one of the greatest honors of my career. Over the past five decades, I have had the privilege of caring for generations of Antelope Valley families, and many of you have become like family to me.

I will miss our visits and the conversations we have shared over the years. I am leaving you in good hands with Dr. Gill and with familiar team members who will be there to help you through this transition. I encourage you to continue prioritizing your cardiac health under his care.

Thank you for the trust you have placed in me. I wish you continued health and happiness.

With warmest regards,
Dr. Shun K. Sunder, MD
