The doctor was thorough in her explanation as to why she asked for a urine sample. People coming in with back pain often have a bladder infections.

I want to sincerely thank my Doctor Sisan for the genuine care, professionalism, and compassion shown during my initial visit. She took the time to truly listen and understand the difficulties I���ve been experiencing with my sleep patterns, fatigue, and sleep apnea symptoms. What stood out most to me was her sincere empathy and patience. I never felt rushed or dismissed. She carefully explained my condition, answered my questions thoroughly, and made me feel supported. Also her attention to detail and concern for my overall well-being gave me confidence that my health genuinely mattered to her. Sleep issues can affect every part of your life physically, mentally, and emotionally and having a doctor who takes those concerns seriously makes a huge difference.

I got there very close to closing and she was patient and got me through xrays. She was able to diagnose my situation completely in a way that I felt comfortable with the diagnosis. And she gave me additional suggestions about my upcoming total mastectomy which was very useful. She is a great representative for UCLA.
