Dr. Lah was very professional and brutally honest. His staff handled the appointment and transfer of medical records in a timely manner.

The office staff, particularly whoever handles scheduling, does not seem to be organized or…read morecommunicate well. On one occasion, I received multiple phone calls in the same day asking why I had scheduled an appointment before my ultrasound was completed. I repeatedly explained that the appointment was to discuss the results of a previous ultrasound, which had already been completed and was in my chart. Despite explaining this several times, they continued to question me. The final issue that led me to cancel my care was when I was scheduled for an endoscopy. No one contacted me beforehand to explain what my out-of-pocket cost would be. Since my procedure was the next day, I called the office because I didn't want to be surprised by a large bill. I spoke with Maggie, and the interaction was extremely disappointing. Rather than listening to my concerns, she repeatedly talked over me while I was simply trying to understand why the office couldn't provide an estimate after obtaining the insurance authorization. It felt like the office was focused on getting paid by the insurance company but not on making sure patients understood their financial responsibility ahead of time. Instead of helping, Maggie told me to call my insurance company or the surgery center myself. I explained that I didn't understand why I had to make multiple phone calls when the procedure had been scheduled through their office. Even after I politely asked her to let me finish speaking, she continued interrupting me and eventually hung up on me. I have worked in customer service for many years, and throughout the conversation I remained respectful. There was nothing that justified ending the call that way. As a result of this experience, I canceled my procedure and will be finding another gastroenterologist. The physician may be excellent, but the office staff's communication, professionalism, and customer service need significant improvement. Based on my experience, I cannot recommend this practice.

Dr. Kara was so kind and insightful--she really listened and made me feel cared for. Staff was…read morefriendly and office was clean and tidy.

He explained everything clearly, took his time to answer all my questions, and made the whole screening process feel calm and stress-free. I felt truly cared for and confident throughout the visit. It's not easy to find a doctor who is both highly knowledgeable and genuinely attentive - Dr. Lee is exactly that. Highly recommend!

Ever since I first met him I felt a sense a calmness, immediately in his presence. He's so…read morethorough, honest and patient. Also, unbelievably knowledgeable. Always asking for consent and personal feedback such as: feelings, thoughts, unlimited of questions. Dr. Lee is genuinely out for us the patients and our best interest. I've met with multiple other GI Docs and left feeling disregarded, minimized, disrespected, confused, and quite frankly treated like a dollar sign. I honestly have never felt more seen and comfortable with Dr. Lee. I don't have one bad thing to say about him or his staff. I highly recommend him! A shout out to Yasmeen. I'm always emailing and calling her, she's so nice, very knowledgeable, patient with me, and so understanding. She works very hard and is on top of everything. I always get a fast response no matter what. Even though it's probably not necessarily her job she always helps me. Not once has she made me bad or an inconvenience to her. She's super friendly, down to earth and still professional. Thank you so much. We need more cool peeps like you and Dr. Lee respectfully of course in the medical field.

He stayed committed to my care and continued working with me until my stomach issues were finally resolved. You never feel rushed or like just another patient--he listens, takes your concerns seriously, and treats you like family. I'm so grateful for the level of care and attention I received and would absolutely recommend him to anyone looking for a knowledgeable and compassionate gastroenterologist.

I'm scheduled for a colonoscopy- I was told that the soonest they could get me in for the procedure is August 21, 2025 I have called to ask for something sooner but his scheduler said nothing sooner and if pain persists go to the hospital. Honestly this was very unsettling. I had blood work done she also stated that the PA signed off on it so if something was alarming I would have gotten a phone call- this is neither reassurance. Initially to get in with the doctor I called for 5 days looking for a cancellation as recommended by the staff to be seen sooner (no success) some of these reviews are scary . Document Everything. I was also granted a referral for the Doctor but I seen the PA . I'm not sure what the protocol is.

Dr. Salaimani is a wonderful Dr.. after my second endoscopy he called and explained the results and…read morethe treatment plan. After that, I had an ultrasound of my liver and found an issue so I made an appointment. Unfortunately I was seen by a nurse practitioner who launched into the results from a while ago that I already talked to the dr. about. I stopped he and told her that I was there for a different issue. She said that she wanted to go over the results from tests done months ago and would get to the liver issue later. Update: No one answers the phone down there and instead an "AI" assistant answers but offers no help. My appointment with the dr has been scheduled 5 months out. The Dr is great- his support staff, including the snotty NP, is not helpful or caring.

No one takes responsibility for the total care of the patient here . The office staff controlled solve, the portal doesn't contain results or provide easy assess to enter information regarding history ,medications etc At My first visit ,Dr Solaimani ordered labs and other tests unbeknownst to me. The office staff scheduled an appointment for me to follow up with the doctor two months after the first appointment for which I had to pay a $70 co-pay and my insurance was billed several hundred dollars. When I got there, they told me I hadn't done the labs the Dr had ordered. I inquired as to why I wasn't notified of the labs at the first visit , there answer was " well we must've had a student who put you in the room and she didn't enter your specific lab you use into the computer " . When I ask about why there was no follow-through on this why no one called me to inquire about why I hadn't had the labs before my appointment, they said oh we don't do that. We don't have any way to know about that. They kept referring to possibly a student that made mistakes the last time I was there. No one wanted to take accountability and they couldn't explain the process of how these things are normally done. It sounds like computers run this office, not thinking responsible people. The nurse practitioner I saw (when I had scheduled an appointment with the Dr) spent only 6 minutes with me informing me "all the results of my previous colonoscopy was normal) something the Dr told me after the procedure. Then ushered me out to schedule another appointment in two months after I complete the labs they had "previously ordered. When I ask about why I didn't see the doctor at this visit, as previously scheduled I was told "oh you have to tell us when you come in so we can put you in the right room to see the Dr." "We don't know who your appointment is with!" This office needs an overhaul from the top down! I feel they just want to schedule expensive procedures such as colonoscopies and EGD's , bill your insurance then dismiss you after they have completed these .I will not return!
