Notice to Patients of Colon and Rectal Care Center of Phoenix


Patients of Colon and Rectal Care Center of Phoenix,

It is with much excitement that Colon and Rectal Care Center of Phoenix, a division of Arizona Associated Surgeons, announces a merger with Advanced Surgical Associates to form Arizona Advanced Surgery effective January 1st, 2021.

Arizona Advanced Surgery, a new entity formed in 2020, will operate with over 40 surgeons and an additional 16 allied health professionals. The providers will meet the needs of the community through a multitude of offices in the Phoenix-metropolitan area with surgical specialties of General, Breast, Colorectal, Bariatric, Trauma, Plastics, Oncology, Endocrine, and Vascular.

For our patients, little will change. Phone numbers, office staff, and locations will remain the same. Since a new electronic health record is being implemented with this transition, all patients, new and established, will need to fill out a few more documents. The new electronic health record will house a new patient portal allowing patients to request appointments, medication refills, complete paperwork, and communicate with their providers. Instructions will be available at the portal link on the website.

We are excited to be on this journey that will allow us to continue to meet your surgical needs. For more information about our specialties and who the providers are, please visit our website at ArizonaAdvancedSurgery.com

Dr. Singh understands the sensitive nature of colorectal conditions, and he is committed to providing quality care to his patients with compassion and dignity.

Modern Surgical Solutions For Your Medical Needs

Dr. Singh uses the latest surgical techniques to treat patients with the full range of colorectal disorders, from simple to complex. He is trained in the most advanced laparoscopic and robotic surgical techniques for the diagnosis and treatment of conditions that affect the colon, rectum and anus. In particular, robotic surgery allows for many colorectal operations to be done more gently than in the past. This is a minimally invasive approach that requires only small incisions, and results in less post-operative pain and quicker recovery.

Specialized training and two decades of experience have provided Dr. Singh advanced expertise in colon and rectal surgery. He offers a broad range of surgical solutions and works closely with each patient to determine the best treatment option for his or her needs. He is committed to helping his patients achieve optimal results and return more quickly to enjoying their daily life.
