5 /5 Dan Mangahas: This Pasadena Endoscopy Center is one of its kind. From the time you enter the center and the time you leave, the whole process is seamless. All employees, nurses and doctors are all very professional, very accommodating and helpful. They even help you to get into your car. I am giving this place a 10 star review. Also, the dreaded endoscopy prep has been upgraded to a very simple and tolerable procedure. With the simpler prep and the seamless endoscopy procedure at the Pasadena Endoscopy Center, endoscopy procedure is now like visiting your primary doctor.
