    Then my second times I met with the receptionist to get all the papers and the prescription for the prep of my colonoscopy.

    I cannot recommend Associated Gastroenterology Medical Group in Anaheim highly enough. From the…read moremoment you walk through the door, there is a level of professionalism, dignity, and genuine human care that is increasingly difficult to find in healthcare. The front-office staff and medical staff are outstanding. They are professional, respectful, organized, and kind. Most importantly, they make you feel like a human being who matters, not a number, an inconvenience, or the next appointment on a schedule. That feeling carries throughout the entire practice. And then there are Dr. Dennis and Dr. Kevin, who are simply phenomenal. Both are extraordinarily knowledgeable, thorough, attentive, and clearly experts in their field. I do not give recommendations like this lightly, particularly when it comes to medical care. These physicians have earned my absolute confidence. There is a sign hanging in the office explaining that appointments may occasionally run behind because some patients arrive with unexpected, complicated, or multiple concerns that require additional time. It asks for understanding because one day, you may be the patient who needs that extra time. Once you experience the level of care they provide inside the examination room, you understand exactly why that sign is there. They don't rush people through. They listen. They investigate. They explain. They answer questions. And when a patient needs more time, they give them more time. I can genuinely say that I would wait three hours in that waiting room without complaint to receive this caliber of medical care. I would much rather wait knowing that the physician is giving another patient the attention they need than be rushed through an appointment myself. If you are dealing with gastrointestinal issues and looking for a practice where expertise and humanity exist in the same building, this is where I would tell you to go. From the front office, to the medical staff, to Dr. Dennis and Dr. Kevin, this practice represents what excellent healthcare should feel like. An unequivocal 10/10. I recommend them without hesitation

The liver doctor at hospital gave him a year to live. After he was released we were traveling to a doctor in San Gabriel which was quite a distance since my parents live in Lakewood, Ca. After searching the internet I came across Dr. Mankal in Los Alamitos and when I say he has been an absolute God send, I mean it!!!! While my father's condition is not without its issues, Dr. Mankal has been amazing. His bedside manner is incredible, he is patient and extremely knowledgeable and best of all my father is still with us, 4 years after the liver doctor at the hospital wrote him off. I also love the portal and usually get answers to questions or requests for meds within 24 hours. I hesitate to post this review because I worry Dr. Mankal will be swamped with new patients but then I think of others facing these types of challenges and needing quality care and feel compelled to share. We also love Angela, his front office lady, she is wonderful as well! I strongly recommend Dr, Mankal and Angela!!!!!

New Patient Process I called the office to ask about their new patient process, and they helpfully walked me through the process and directed me to their online forms. After filling out the online forms and submitting them via email, I was able to call the office and have someone on the phone to help with questions. Super nice and patient staff members! They also responded to my patient forms same-day, and my first appointment was scheduled within a week. Appointments The patient portal and ability to use televisits is really convenient. I am not a tech-savvy person, and I was able to setup my account online, pay online, and virtually meet Dr. Mankal in a televisit. Patient Care Dr. Mankal listened to all my concerns and was able to describe what was happening in a way I could easily understand. He prescribed clear directions for next steps, and a prognosis. I really appreciated how clear and attentive he was.

    It started off well. I had a consultation appointment. I then had a colonoscopy and an endoscopy,…read moreon October 1, 2025. I went to the follow up appointment 2 weeks later. I was told I had Pylori. A stomach infection. He prescribed three medications. I deliberately reminded the doctor I take Methotrexate. Many medications do not interact well with Methotrexate. He said it was fine. I picked up the three medications the next morning. The pharmacist said I should not take these medications. I told her the doctor said it was fine. I should have listened to her. I had lunch and took one of each pill. By 4.00pm, I thought I was going to die. My heart was racing, sweating, shaking, severe nausea. Dry heaves. I'm a widow, and there's usually no one here at that time of day. By a miracle I had a friend here that day. He wanted to call the paramedics. He got me water, and sat me down in my hay barn, as I couldn't stand up. I was terrified. I drank a bottle of water. He managed to drag me to my house and by 4.30pm, I was in bed. I'm diabetic. I had no dinner, and took no meds. I've never felt so bad in my life and I'm 77 years old. I kept drinking water to flush the meds, most of the night. I called Dr Shen at 9.00am the next morning. The person I spoke to, said she would send a message to the doctor. That was 2 weeks ago. I never took another pill. I spoke to my GP, who said not to take them. Dr Shen, or anyone from his office, never called me until yesterday. October 28, 2025. I had already made an appointment with my previous gastroenterologist whom I should have gone to in the first place. I went to Dr Shen as he was local, and I could avoid the drive to Orange County. Big mistake. It wasn't even him calling, but someone in his office. I told her I wasn't interested in anything they had to say, as they abandoned me two weeks ago. I'm disgusted with the lack of compassion or any communication. I was just a number on their conveyor belt. I'll never go back there. I have all the reports which I will give to my original gastroenterologist and move on.

    Very good Dr. Explain everything and had the patience to repeat what ever you don't understand. I…read morehardly recommend him.
