Our Philosophy

Alinea derived its meaning from the latin word which means “off the line”, this symbolizes a new beginning, a new way of thinking.

Dr. Ammar’s philosophy of “ideal” health began during his involvement in high school team sports.

He realized that getting the most fulfillment out of life centered not only on being free of disease but also in achieving holistic health, happiness, confidence and being able to provide care to others. In fact, Dr. Mahmoud always admired the joy that his parents experienced from being physicians and helping their patients.

During his time in Biomedical engineering.

Dr. Mahmoud focused on the promising future of tissue and stem cell engineering.  He gained valuable insight on how regenerative and preventative medicine can impact our health in order to improve our quality of life.

Dr. Mahmoud continued his education in medical school where he realized his passion for OBGYN and surgery.

OBGYN residency piqued his interest, particularly in minimally-invasive surgery. During his attending years he combined his past training as a biomedical engineer with advanced medical techniques. As a physician, his goal was to offer his female patients the best in minimally-invasive surgical procedures from a functional and cosmetic perspective.
