After some research and speaking to my internal medicine physician, they are suggesting the following specialists:

Cardiologist: Dr. Kevin Rapeport in San Diego
Ascending Aortic Surgeon: Dr. Pedro Catarino, MD, Director of Aortic Surgery in the Department of Cardiac Surgery at the Smidt Heart Institute (Cedars-Sinai)
Vascular Surgeon for All Other Aorta Issues: Dr. Ali Azizzadeh, MD, a leading vascular surgeon at the Smidt Heart Institute (Cedars-Sinai).

I hope this helps.
