Hello, my name is Sultan Ayoub. In 2003 I graduated with a Bachelor of Science in Nursing from Eastern Michigan University. I was hired as a home health care nurse in the first transcultural home health care program in the world. In 2006 I was hired as a travelling nurse and was relocated to San Diego and then Chandler Regional Medical Center. After my contract expired at Chandler Hospital they offered me a full time charge nurse position which I accepted and permanently relocated my family to Arizona. In 2007 while working full time and starting a family I attended the University of Phoenix to complete my Masters in Nursing. In 2009 I completed my Masters and became a board certified Family Nurse Practitioner. For almost a year I trained extensively in pediatrics with Dr. Charles R. Martin Jr. before starting employment with him at Southwestern Pediatrics. In 2009 we opened the first pediatric office in Maricopa to provide the community with excellent and compassionate medical care. I consulted with the school nurses when needed for all 11 schools. I am married and have two boys  who keep me active and very entertained! I can truly say I love my job and all our patients! I look forward to continue to care for the future of our Maricopa children.
