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.

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.

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.

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!

From the moment I arrived, every single staff member treated me with kindness, respect, and genuine care. In many service environments, there is usually at least one person who seems rushed or disengaged--but that was absolutely not the case here. Every person I encountered was professional, warm, and attentive. What stood out most to me was the culture of the entire team. You could clearly see that how they treat their patients and how they treat each other is extremely important to them. The staff worked together seamlessly and treated one another with respect and positivity, which created such a welcoming and comfortable environment for patients. Even in a medical setting--which can sometimes feel stressful--the team created an atmosphere where people could laugh, feel at ease, and feel genuinely cared for. I observed them treating every patient with patience, dignity, and compassion. Having gone through many medical procedures in my life, I can honestly say this is one of the best healthcare experiences I've had. It's rare to see an entire team operate with this level of professionalism, kindness, and excellence. Thank you to the entire staff at ACE Endoscopy and Surgery Center for making patients feel valued, respected, and appreciated.
