GLENDALE, AZ, SEPTEMBER 19, 2019 – Furthering its commitment to deliver high-quality, coordinated medical care to the residents of the Valley, Summit Medical Group Arizona (SMGAZ) announced today the addition of two primary care physicians in Phoenix and an endocrinology specialist in Glendale.

“The face of medicine is changing all the time,” said Kent M.

I'm looking forward to advocating for all our patients we serve.”

Dr. Merchant, one of SMGAZ’s two new internists, earned his Doctor of Medicine at Georgetown University School of Medicine in Washington, DC. Dr. Merchant provides exceptional patient care that incorporates the specialties of internal medicine, and pediatrics.

“I am excited to join Summit Medical Group Arizona,” says Dr. Merchant. “I value my relationship with my patients and I’m always honest with them. I will always provide my patients with a comprehensive treatment plan that best fits their health care needs.”  He is located at 5620 W. Thunderbird Rd., Suite C, in Glendale.

He provides general health services, including physical exams, sick visits, disease management, pain management, and minor in-office procedures and surgeries.

I think the care and comfort a patient receives plays a big part in the healing process,” states Dr. Slovak. He provides services at 9150 W. Indian School Rd., Suite 118 in
