    The website information is poor. I wanted to fax a patient referral for an appointment, but no one at the practice knew the rheumatology clinic’s fax number. They kept giving us phone numbers that were not fax numbers and belonged to other clinics. Completely unhelpful.

    The second-floor desk provides terrible service. The older woman checking patients in failed to register me for my second appointment with the same doctor, and I waited in the waiting area for over an hour while patients who arrived after me came and went. I saw late patients told they were late but still seen. The third time I stood up to complain about the long wait, I learned they had marked me as a “no call, no show” and canceled my appointment because of the receptionist’s mistake. I had checked in 10 minutes before my infusion appointment, yet they only saw me after canceling it. During my entire infusion, a woman sat in the infusion area talking loudly on the phone and no nurse asked her to hang up. At my second appointment, an accident made me arrive beyond the stated 15-minute grace period by 12 minutes. I then had to wait in a long check-in line with only two receptionists. I reached the desk at 9:29, and when she called the infusion area they had marked me as a “no-show.” I acknowledge that I was late, but they offered no courtesy despite my prior history with them. I wanted a referral from this company, and members of my family also work for it. As a person of color, this was disappointing but expected. A white woman with the same 9 a.m. appointment arrived just as late or later and was given ample grace. Message received. I will take my insurance elsewhere and make sure this review has an impact.

    I wish I could give zero stars! The second-floor front desk is terrible, especially Esteban! I have never received worse service. It takes months to schedule a new-patient visit, and because I waited 15 minutes before anyone came, they removed me from the schedule and said I had not shown up. This place needs better service and better staff.

    Orthopedics at 3030 Westchester Avenue is terrible and has no regard for privacy. The nurses come into the waiting area and ask patients questions where everyone can hear. I asked to speak privately, and the woman was extremely rude. I have never been treated so poorly. HIPPA exists for a reason. I heard another patient say the same thing. I like Westmed, but this department needs improvement.

    I waited nearly three months to see Dr. Ali. The appointment reminder listed 3030 Westchester Avenue, but entering that address in Google Maps leads to the wrong location (see screenshot!). I ended up at the wrong place, which was also a medical building, and realized the mistake only after 10 minutes. I called the office, drove to the correct location, and arrived 16 minutes late. Although this was caused by a known address error, the staff were rude and unpleasant. They made me wait 15 minutes before telling me the doctor would not see me that day and that I had to reschedule for another month and a half later. This was extremely frustrating, especially since I had completed bloodwork days earlier, arranged childcare, and spent extra time in traffic because I do not live nearby. It is unacceptable for the practice to know about this address problem yet do nothing to correct it or provide accurate directions. I hope Summit Health resolves it so other patients’ time is not wasted.

    I am surprised to see so many negative reviews. Everyone I encountered in the lobby and on the third floor was very friendly and welcoming. I waited only two minutes before my name was called and I was taken to an exam room. My only complaint was that the music in the waiting area was too loud, which is why I deducted one star.

    Friendly, helpful staff.

    Ample parking, easy access near I-287, bright lighting, no wait, plenty of seating, and specialists are always on time. The clinic, including the restrooms, is clean. There is a café serving food and drinks, and appointments are easy to schedule.

    I had a very poor experience with the front desk at this physical therapy clinic. The staff member I encountered was dismissive and repeatedly interrupted me, making communication extremely difficult. Professionalism and basic respect should be expected in a medical setting. Instead, the interaction made me so uncomfortable that I ultimately left without receiving help. Management should seriously review front-desk conduct and customer-service standards. First impressions matter, and this experience alone was enough for me not to return.

    Grace came here, but Dr. Yue in rheumatology did not see her.

    I received and replied to the confirmation message. It took me 20 minutes to get there, and I had taken a day off for the appointment. On arrival, they said they did not accept my insurance. I offered to self-pay, as I had done many times before, but they refused me this year. The receptionist had no customer-service skills, and despite knowing I had a medical condition, no one was willing to help. I will never return and will tell others not to waste their time.

    Everything was fine until the surgery part. There was a lot of nonsense, but I hope my surgery goes well 💯

    If I could leave a zero star review, I would. I have very low iron and need iron infusions, which I received 2 years ago. The doctor I saw then is no longer with the practice and I was forced to wait over 2 months to see Dr. Levin, who spent less than 5 minutes speaking to me. He clearly had not read my medical records and asked me questions that he would have known if he had taken 2 minutes to look through my records. He then proceeded to tell me that low iron was not causing my fatigue, despite the fact that this is not the first time I am dealing with this issue. On top of that, I walked out of the appointment without any appointment for an infusion. Dr. Levin is not able to write orders, so another doctor has to actually put in the order for the infusions, which will then be approved by my insurance, and then someone will call me to schedule the infusions. So I am no closer to getting this issue resolved than I was over 2 months ago when I first called. I have seen a lot of doctors over the years, but I have never felt so dismissed by a medical doctor. He had no interest in listening to anything I said and no interest in doing anything to resolve the issue. I have numerous doctors at Westmed/Summit Health and have generally been happy with them, but the hematology department in Purchase is horrible. Don't waste your time there.

    I am very disappointed with this clinic. Its phone service is a complete waste of time and shows no respect for anyone's time. I had to call repeatedly about the same issue. Because I was transferred among different operators to “reach the right doctor,” I had to provide the same information three times. Even when the mistake was theirs, they lacked the courtesy to correct it. A patient's suffering does not matter to them. I was very satisfied with the doctors and nurses I saw. I am not surprised that many professionals leave because they are expected to prioritize quantity over quality. I also would not be surprised if many patients left, because this feels more like a fish market than a medical facility. Although they promised a same-day callback, 32 hours have passed and I still have not heard back, and now it is the weekend.

    好医生都走了!!!! 骨科运转良好,效率很高,等待时间不到10分钟。 理疗科非常忙,但他们很棒,非常细心,致力于帮助所有患者恢复活动能力。与家庭医生的沟通几乎不存在。我退休的医生之前会打电话告诉我化验结果,也会在我留言后回电,但现在既没有电话也没有留言告诉我验血和常规检查结果。所以我猜想,一切都还不错。

    员工态度恶劣,客服中心简直是个笑话!太不称职了! 西区医疗中心(West Med)的医疗质量正在急剧下降!这些变化简直糟糕透顶。我要退出这个医疗系统。这些变化似乎是在暗示我应该另寻其他医疗机构。

    等待时间简直糟糕透顶。我去输液,护士为了找血管,把我胳膊都弄坏了。完事后,他一把扯掉胶带,把导管也拽了出来。我终于明白为什么他们的评价这么差了。

    我这次试管婴儿尝试的经历非常令人沮丧。之前有人评论说他似乎不记录你的病情细节,确实如此,他总是问同样的问题。 问题在于,过程中出现的任何错误都被立即归咎于我,让我觉得自己像个笨蛋,连指示都听不懂。最糟糕的是打促排卵针的时候:所有针剂、每一步要用的材料都应该事先解释清楚,而且我应该有一份清单,确保所有东西都准备齐全。我打电话给药房,他们送来了药物、针头等等,但我却无法检查所有东西是否都到位…… 促排卵针的注射时间安排得糟透了,晚上11点45分。半夜我才发现针头尺寸不对,不得不凌晨1点去CVS药店买针头打针(我本来第二天要早起上班,但听说医生时间很紧,我可以把整个过程都告诉你)。所以我凌晨2点才去打针,严格按照指示操​​作。取卵手术必须在曼哈顿市中心进行,交通拥堵,停车费还要60多美元,这些都是不得不面对的问题。手术后,他们没能取出卵子。当时我疼痛难忍,他们又一次质疑我是否能听懂基本指示,我不得不跑回哈里森医院,让他的护士汉娜给我配好合适的剂量。好吧,我回家后,凌晨两点严格按照指示注射了药物。 下次预约时,我非常焦虑,因为上次尝试失败带来的疼痛,加上12个小时以上不能吃不能喝,结果他们又用一种探究的语气告诉我激素水平不正常。当时我的腿还抬着,不得不进行阴道穿刺,因为之前已经抽过一侧的积液,所以这次穿刺疼得要命。结果发现,是他的护士没有按照他“做”的,她犯了错,但他们之间难道没有任何沟通吗?更糟糕的是,他们还收了我们3000美元的胚胎冷冻费用,而这笔钱根本就不存在。现在我们还得想办法把这笔钱要回来。整个过程简直是浪费时间、金钱和精力。我强烈不推荐这家诊所/医生。附注:这种激素类药物会导致剧烈的情绪波动,但这一点却无人提及。

    This is not where I went, but he helped me. Now I have two lovely children.

    He did not monitor my HCG levels, resulting in an ectopic pregnancy that required emergency surgery. I have seen several IVF doctors and do not recommend him.
    Dec 24, 2025
    I had an extremely poor and ultimately painful experience with this IVF doctor. Throughout treatment, my reasonable concerns were repeatedly minimized or dismissed, making me feel manipulated rather than supported. The doctor often seemed unfamiliar with my condition, could not remember which tests had already been completed, and questioned or minimized diagnoses from other specialists involved in my care. Despite my underlying health conditions, the doctor pursued an aggressive treatment plan that significantly worsened my condition and caused additional health complications. I did not feel that I received the individualized care appropriate for a complex case. Communication was also extremely poor. Distressing or serious news was delivered through the patient portal rather than in person or by phone. Appointments were frequently delayed because multiple patients were booked for the same time, resulting in long waits. One especially upsetting incident occurred after I was told that I had developed a complication. The doctor placed a hand on my shoulder and told me to "smile." This was inappropriate and distressing. Overall, the experience caused lasting emotional trauma and physical health problems. I later underwent IVF at another practice, where the attention, communication, and respect were far superior. Even more frustratingly, two years later we were charged embryo storage fees despite having no viable embryos to store. This was deeply upsetting and further undermined our confidence in the clinic's administrative processes. I would not recommend this doctor to anyone with a complex condition or anyone needing attentive, individualized, and compassionate care.

    Dr. Keltz is the best doctor I have encountered in any field. He is highly professional and a true expert in his specialty. From our first appointment, when we knew nothing about the process, we were impressed by his warm bedside manner and the clinic's excellent organization. Efficiency and professionalism define the entire practice. Everything ran like clockwork—there were never missing lab orders, appointment errors, or calls that failed to come—and I always felt cared for by everyone in the office. I had never received such professional medical care. Dr. Keltz even personally performed my egg retrieval on a Sunday morning while a hurricane warning was in effect in Manhattan! I always felt the staff cared about me and genuinely wanted me to become pregnant. We are very glad we chose WestMed and Dr. Keltz, and I recommend him wholeheartedly. I also enjoyed receiving care at WestMed. Because everyone there is so professional, not only in Dr. Keltz's office, I began seeing other doctors at their White Plains location. I am happy to receive excellent care close to home, in a convenient location, with everything covered by insurance!

    I cannot say enough good things about Dr. Keltz. I have been his patient since 2020, and he helped us achieve our dream of having a family. He is direct but kind, funny, and always meticulous with my treatment plan. He genuinely cares about his patients and does everything possible to help them become parents. Highly recommended!

    I am extremely grateful to Dr. Martin D. Keltz and his team. Their expertise and support helped me realize my dream of becoming the mother of two wonderful children. Dr. Keltz's expertise and unwavering support were essential throughout this incredible journey. I am deeply grateful for his excellent work. If you are looking for an outstanding reproductive endocrinologist, Dr. Keltz is someone you can trust.
