★★★★★ My wife and I have been patients at La Vista Medical Center for a while now, and I can't say enough good things about the care we've received. Dr. Hajjal (my doctor) and Dr. Khaleel (my wife's doctor) are both incredibly caring providers who genuinely go above and beyond for their patients. What really sets this practice apart is how they follow up after treating an issue—they actually check in to see how you're doing, which shows how much they care about their patients' wellbeing, not just the immediate visit. We also had a stressful situation during my wife's pregnancy when our medical group changed and we ran into coverage issues. The staff, especially Ms. Saisa, worked hard to help us navigate everything and made sure my wife didn't lose access to care during such an important time. She didn't just resolve the issue and move on—she personally followed up with us afterward to make sure the coverage was actually sorted out and that my wife was still able to get the care she needed. That extra step gave us real peace of mind during an already stressful time. If you're looking for a medical practice where the doctors and staff truly care about you as a person, I highly recommend La Vista Medical Center.

I've recently established care with Dr. Hajal as my PCP and have had a great experience. He takes the time to listen, explains things clearly, and never makes me feel rushed. He went over my lab results in detail and made sure I understood the next steps. As a healthcare professional myself, I appreciate how thorough and knowledgeable he is. It's not always easy to find a provider who is both competent and easy to talk to, but Dr. Hajal is exactly that. The office is clean and well run. I've done both telehealth and in-person visits, and communication has always been easy. Saisa and the rest of the staff are professional, friendly, and very helpful. I'm glad I found Dr. Hajal and would definitely recommend him to anyone looking for a primary care physician.

Dr. HAJAL is a very caring and a great doctor. He always takes the time to explain what could be wrong with you properly when you get lab results and He is never rushed as far as my experience goes with him. He has given me great advice with my health. He also cares about what medications I should be taking. He asks a lot of questions in how you are feeling every time I see him. His staff is always busy perhaps because He is a great Dr. I am glad I found their practice..
