    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.

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.

They never sent a cancellation email. They sent a text from a 707 area code to cancel the appointment. 707 area code looks like a spam text. Why did they not communicate thru emails. Poor, pitiful customer service. Do waste your time with these clowns.

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.

I experienced some throat soreness yesterday evening, but thankfully, it has subsided today. Last night, I felt some bloating and discomfort in my abdominal area, which persists today, albeit without any significant pain. Despite this, I was able to resume my normal activities today, which is made easier by the fact that I am currently on summer break. Following the procedures yesterday, I was informed about certain protocol guidelines for my condition. It was discovered that I have diverticulosis and some hemorrhoids. I must express my admiration for Dr. Solaimani, who is an exceptional gastroenterologist/surgeon. During my follow-up appointment, we will discuss a 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.

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.

For months & months he was sent for internal cameras, drinking barium for tests, & Dr Berry prescribed tons of pills. Convinced husband son was faking it when my son DESPERATELY needed his Dad's support We almost got divorced over how he then daily treated our son until I went to a GREAT DICTOR I took my son to Dr Galen Huang. Kept interrupting me during case history "did Dr Berry EVER bother to do a quick & cheap lactose intolerance test ?" NO DR BERRY DID NOT. 10 minutes with Dr Huang and my son was almost "cured". Super quick test showed my son was massively lactose intolerant ! Any guess what all the drug companies use as a cheap filler in all their pills Berry prescribed? LACTOSE !! Dr Berry did NOT do a totally non-invasive and 1st step inexpensive test that takes less than 3 hrs sitting in a waiting room after drinking a solution in a cup. NO !!! The "wildly expensive cure" ?? Cheap generical over the counter lactaid pills before milk, ice cream, cheese etc . Oh and my son & his father - over 30 years later - have never again had a good or close relationship. My son's 4 siblings were so upset over how my husband treated me their brother when he was so sick almost every single day that they too have a pretty bad relationship with their father.
