Optum Gastroenterology - Lake Success - Marcus Ave

Very wonderful experience! Dr. Ahmed and his entire team were phenomenal, professional, and incredibly welcoming throughout my colonoscopy and upper endoscopy. The procedure was quick, efficient, and well organized, which made me feel comfortable and at ease. They also provided medication samples, which I truly appreciated. I had an excellent experience from start to finish and highly recommend Dr. Ahmed and his team for their outstanding care.

Dr. Berger and his entire staff were excellent. I highly recommend using them .

The staff at doctor’s office was informative and provided details of the entire procedure. The anesthesiologist was attentive. Upon completion of colonoscopy and endoscopy, the nurse arrived offering drinks and snacks. Dr Eleazer yousefzadeh explained how I would feel in the next few days and what to expect. I am satisfied with the process.

Dr. Haas has provided exceptional care for our family. He is incredibly knowledgeable, experienced, and compassionate, always taking the time to listen and make us feel comfortable and reassured. What stands out most is how genuinely caring he is — treating his patients like family. We first saw him when our little one was just 2 months old and struggling with severe CMPA, eczema caused by food allergies, GERD, and difficulty gaining weight. As first-time parents, we were overwhelmed and struggling ourselves. Dr. Haas took the time to find the right formula for our child and consistently checked in on his progress and well-being. Fast forward to 17 months old, and our little one is now free from GERD, CMPA, and eczema, and is thriving. He went from the 10th percentile to the 94th percentile in weight. While children can outgrow some of these conditions, we truly believe having a doctor who is willing to dedicate the time, care, and effort to finding the best treatment makes all the difference. We highly recommend Dr. Haas to any parent looking for a compassionate and wonderful gastroenterologist for their child.

While I was not a patient at this office, I accompanied a family member who was having a procedure done. During our time in the waiting room, Dr. Haseeb Ahmed came out and reprimanded a front desk employee in front of everyone present. There were approximately nine people in the waiting area, along with several other office staff members who witnessed the interaction. Regardless of the issue, it was extremely unprofessional to address an employee publicly in that manner, especially someone who appeared to be new. Workplace concerns and corrective conversations should be handled privately and respectfully, not in front of patients and visitors. The interaction created an uncomfortable and hostile atmosphere in the office. Based on what I witnessed, I would not recommend this workplace environment to prospective employees.
