Patient Reviews
Jan 14, 2026
My primary care doctor recommended her partner for a routine colonoscopy. Office was terrible about responding to my request for an appointment. Finally learned that Dr Abramson was heavily booked, & was referred to Dr. Al-Sayeed instead. I had no contact with her prior to my procedure, other than a note to pick up the prep material from a pharmacy. After the colonoscopy I had problems, but did not receive a response to my phone calls or through the portal for days. I made several attempts, & finally received a cursory written response, which left me with further questions, & no answers. Finally got help through a very nice PA. The whole experience left me extremely frustrated with office staff & Dr. Al-Sayeed. No way I could recommend this practice, except for the PA & the office nurse.
