Patient Reviews
Mar 06, 2025
He’s been such an amazing doctor though and through. He helped my mother throughout her procedure. He cares about his patients and I could tell throughout my interactions with him. I was skeptical of doctors at first since I had a few bad experiences. But Dr. Hallak proved that some doctors such as himself do care. I will forever recommend him to anyone that’s skeptical or want a doctor that cares, because he does care.
