Why Choose Us

“Let us help you through your steps in life.”  This is the philosophy of Allied Associates OB/ GYN.  In 2007, the board certified physicians opened their practice to provide comprehensive medical services for women from adolescence, through child bearing and menopausal years.  The practice services range from primary obstetrics and gynecology with a strong focus on preventative & routine care, to some specialty services dealing with women’s reproductive disorders, urinary incontinence, abnormal menstrual bleeding, etc.

The doctors have many years of clinical experience and office practice, and serve as instructors of residency training in teaching facilities throughout the St. Louis area.  Assisting the physicians is nurse practitioner, Ashley Merlati and a highly skilled group of registered nurses, ultrasound technicians and medical assistants.  

Drs. Boyd, DeRosa, Herrmann, Shores, and the staff support their patients while providing the highest quality of care for women of all ages.
