    I have an extensive problem list which is complicated by newly emergent health issues. Dr. Halaseh listened to me, conducted some research during the visit, and discussed the science and next steps. He did not minimize my concerns and did not offer hollow reassurance. I appreciate that he collaborated with me.

  • May 13, 2026

    Dr. Halaseh is outstanding! My initial visit with him a couple years ago motivated me to make MedStar my one-stop-shop for all medical care.

  • Apr 25, 2026

    Dr. Halaseh is one of the best doctors I've seen. He genuinely seems like he cares and wants to help. He's thorough and I've never felt rushed.
