When I first walked in the young lady behind the counter greeted me with a warm welcome.
Then I was called to check my stats; weight, height, etc. The gentleman assisting me there was extremely polite.
Once I was in the waiting room, the young lady with the most gorgeous smile walked in and did my ECG. Leslie had on a mask but one can tell there's a ray of sunshine in her smile. Always so polite and the way she explains what it is she is about to do. Is truly amiable and courteous. Leslie Castro makes you feel at ease. Thanks again for whoever hired Leslie. You all did a great job.
Now Dr. Simon, let me say he is a phenomenal doctor. How can I not recommend him to anyone. Especially with the staff who work with him. Dr. Simon thanks for your expertise and it's always a joy.

His nurse was very friendly and accommodating of my disability. The lab person was nice professional and fit me in for a pre-op blood test on the same day appointment so I would not have to come back another day.

This is only the 2nd time I’ve seen Dr. Simon. First was supposed to be for a complete annual physical. This one, 6 months later, was a follow up. Dr. Simon does appear to genuinely care about my care, and offers practical advice and guidance. However, I feel like the actual physical part was minimized. We spent both sessions just talking and I was in and out in about 15 minutes. Often feels rushed. Giving 4 stars because again he seems to care and likely he was rushed or overbooked. Willing to give him more time to see how it works out over time. Next follow up in 6 months so let’s see.

I was a new patient. My health plan called the doctor's office. The receptionists said they were taking on new patients so I show up to make an appt. Same receptionist says I have to wait 2 months. I won't wait more than 2-3 weeks That's my policy. If I have symptoms or if i'm sick, I need to see my doctor. And if I have to go to urgent care, I will, but i'm not gonna wait 8-10 weeks. The doctor is still young. He has lots of time to build his patient file.

Dr. David Simon was extremely unprofessional with my wife. My wife went in as a new patient to seek professional help, and when Dr. David Simon realized my wife is Palestinian he made a handful of bigoted remarks toward my wife and toward all Palestinians and allowed his geopolitical and personal opinions to prevent sufficient patient care. We are absolutely disgusted and astonished that this behavior took place in a professional healthcare setting.

Rafael G.
Most frustrating doctor’s visit I’ve ever had. Never had a doctor brush off my concerns the way this doctor just did. After a 1 min conversation, he quickly stated, without any other recourse or problem solving, that he could not help me and would refer me to someone else. By the way, always been healthy, never on meds, but have been experiencing brain fog and focus issue since COVID. Something is off with my brain performance and this doctor seemed to care very little about my request for help. Advice, at least pretend to care. I would probably trust your judgement if you showed an ounce of interest to help me.
