Good vibes and positive energy all around. Doctor Naim is super down to earth and seemed to legit care about my concerns.

Verified patient
I've made the appointment for 1 of our CTs who was super nervous. She called me right after to tell me how wonderful this whole team treated her. Thank you!
Verified patient
The office was very clean and parking was easy. The doctor was kind, although I wish he would have asked more questions or had more curiosity. He made a lot of assumptions about me and I don't feel closer to understanding what is wrong. I do have clear next steps which I appreciate. I am willing to continue to see this doctor to see if his approach works.
Great doctor, great experience. Easy office to get to, friendly staff, I was seen upon arrival! I felt very comfortable discussing my concerns with the doctor and found him to be quite knowledgeable, caring, and efficient. Thank you!
Verified patient
Great
The staff is horribly disorganized. My medication, as prescribed by this doctor, requires prior authorization—which I informed them about and they disregarded by saying "we will see"—but despite calling twice a week for almost two months, they have still not filed the prior authorization forms. They forgot to charge me for my appointment until I reminded them. I have never seen an office run this poorly as a patient. I strongly encourage people not to see this doctor.
I would go back. Clean and bright office.
Verified patient
First visit, Dr. Naim helped me feel a little bit of relief regarding my situation. He let me know that there is a new standard for the issues I have and it’s possible I could change my medication, which was making me feel sick and wasn’t a good long term solution. Also, he’s very nice and easy to talk to.
Verified patient
Felt listened to. It was vital for me as a patient to voice my concerns and have a serious discussion with my Doctor, Dr. Naim addressed my concerns and created a plan specific to my medical history, I feel comfortable that I am on my way to getting the answers I need,
Verified patient
Not the best and not the worst. The provider took an incomplete history, no social history and did only a cursory exam. He seemed to have his conclusions in mind before I even got there, and mostly recommended adding tests I'm not sure were needed that he would perform at added costs. Eye contact was poor and overall bedside manor could use some work, explanations lacking. I was not confident he really knew what he was doing. While not the worst, I felt like he was overselling procedures and not really on top of the problem.
.
Dr. Naim and his team saw me even before my allotted time and took care of my needs immediately. They efficient and effective!
Attentive doctor that listens and cares.
Dr. Naim is very Professional. He has listened to everything I have said with concern. He is fantastic!!! I would definitely recommend him. I choose my Providers by their knowledge and professional.
Dr Naim is very professional, kind, and a good listener. He listened to me explaining my symptoms and constant pain. He explained the results of my MRI clearly, and what needed to be done.
Verified patient
Very disheartened by my experience with Dr. Naim. I'll preface this review by mentioning while I waited to be seen, I saw a medical sales rep show up/speak to office folks and drop off samples. I didn't think too much of it at the time except that the optics of it look weird. Once I see the dr, he asks me the perfunctory questions. I see him checking his watch a few times and I already have a sour feeling. Next thing, the course of "treatment" is try out various meds to see which ones work best. Then he gives me some samples. He didn't try to determine any other potential root causes or even ask if I wanted tests run. Before I drive out, Dr. calls and asks if I got an exam done. Weird question to ask since he was the only Dr. to see me and knew he didn't perform one. I go back up to the office and he does an exam. I debated writing this review but I think it's important for drs to be held accountable and not make their patients feel like guinea pigs or worse, just another statistic.
I was asked questions I hadn't been asked before about my situation and I truly appreciate the interest and exceptional knowledge. I felt at ease the minute I walked in.
Dr. Naim was very helpful and assessed my condition quickly, providing peace of mind and a plan for moving forward. He made sure to explain his diagnosis and next steps.
Verified patient
Dr. Naim was personable and thorough in his questioning of my symptoms. He answered all of my questions, scheduled a follow up appointment, ordered some labs for me to complete & gave me numerous tips for dealing with my sour stomach/ stomache-aches in the meantime. The office parking was affordable, easy to navigate, and his nursing staff was friendly & helpful.
Verified patient
Dr Naim was very friendly and professional. His staff were friendly and courteous. I was seen on time. The documents I completed in advance were accepted along with my insurance.
Simply amazing doctor. This is my first visit. My file was ready and fully reviewed prior to the meeting. He was patient in answering all my questions and concerns. His clear communication style made complex medical information understandable. I felt reassured and confident in his care throughout the treatment

Great experience
Verified patient
It was a pleasure to meet Dr Naim. Thankful for him masking for me, as I am high risk for Covid. He was very easy to talk to, and listened very carefully to everything I had to say about my issue. Handily answered my questions, and was very personable in his demeanor. I appreciate the strategy he offered and feel im in good hands
The doctor was good and listened carefully. The problem started after we scheduled a colonoscopy, I was supposed to receive a prescription which I never did. I tried to contact the office a few times, left voice mail, sent an email and never got a reply from them. As I did not receive a prescription I could not prepare and missed the procedure. Even after the day of the procedure I never received any call, I cancelled the next appointment with the doctor and the procedure took around 2 months of my time.
Great experience! Doctor listened to concerns and had a keen awareness of what is probably going on with my GI tract. I didn’t wait long and the follow up appointments were scheduled with the very friendly women in the office. They made sure to book me at a surgical center that was fully covered by insurance since he works with multiple locations so I appreciated them being mindful of that.
My visit with Dr. Naim was really great, he was very intent on listening and exploring everything to properly recommend testing and reach a diagnosis. I am looking forward to working with Dr. Naim to figure out my issue.
Verified patient
Excited to have found such a caring doctor with Dr. Naim. He was very present and caring. I would totally recommend any of my friends to this practice.
Verified patient
Came in just to request specific testing to look at with my homeopathic doc, but Dr. Naim had a very affirming vibe, so I got into all of my symptoms and experiences that had previously been responded to by GIs with things like "I dont know but let's try antibiotics" or "It sounds like it's mostly a mental issue". Dr. Naim was so validating, ordered testing and shared knowledge about what was normal and what was not without giving me a long list of potential diagnoses, which was soothing to me. He was also very validating about me not wanting to do antibiotics, mentioned that he also employs natural remedies, and he even asked to see my tongue which I would not expect from a western doctor! Overall it was a wonderful visit, and I'll hopefully have more information about my health and a treatment plan within a month! The other workers in the office are very nice as well, though if you're booking on zocdoc don't bother doing the paperwork online beforehand, you'll have to do it irl.
My visit was super easy, the staff was super friendly. Had an appoinment and arrived early since it was my first time there. The doctor was 10/10, asked me all the necessary questions and explained everything in fine detail for me to understand. He made me feel confortable which is what you want from a doctor. Have a following up visit in a couple weeks and I am sure the experience will be the same or better.
Verified patient
Dr. Naim was excellent. I was able to get an appointment the next day and it was a great experience. He listened carefully and came up with a care plan that took care of all of my needs. The office was very clean and professional,? Plus the staff was friendly and helpful. I strongly recommend Dr. Alan Haim MD.
Verified patient
The doctor was very nice. He took his time to listen to everything I said, read the papers I brought with me. Was very courteous and attentive. He did not rush to other patient and answered all of my questions. He appeared to be a knowledgeable doctor.
