Dr. Mark Haltrecht is a board certified family doctor practicing medicine in Nassau County, New York.

On February 28th, Dr. Haltrecht left his prior place of employment joining forces with Dr. Susan Groh  to create a new practice in Merrick, NY.   The Doctor’s Office opened its doors on March 10th, 2014 offering family practice, holistic health, and immediate care services.  Dr. Haltrecht will still provide great, friendly service in a bustling modern office and there will be no change in the health insurances that are accepted.   Walk-ins will be accepted for immediate evaluation and care, and appointments for your favorite provider will be also be honored.  The new practice will also offer web based virtual doctor visits, secure internet access to medical records and test results, as well as the ability to email your provider.

Our mission is to provide great health care for your entire family with fast, courteous service, and as little a wait time as humanly possible.

Feel free to have your medical records faxed to the above number and you can stop by or call to make an appointment.  See you soon!!!!
