  • Dr.
    Nejat Destani

    I'd Like to introduce myself, I’m Dr. Destani. I’m one of the Family Medicine Practitioners at Primary Care Associates. Since the age of three, It’s been a lifelong dream to help people. I was able to achieve that goal by becoming a physician. I enjoy seeing patients from newborn all the way to geriatric. When I have free time, I like to spend it with my family which includes my wife, four children, two daughter-in-law’s and four grandchildren.

  • Dr.
    Lori Weiss

    Dr. Weiss, as a general pediatrician at Primary Care Associates since 2002, sees children from birth until 19 years of age. She believes that as your child’s physician, she should act as an advisor and advocate for your child’s physical and emotional development. The most gratifying aspect of pediatrics for her is to watch young infants and toddlers grow and mature throughout their childhood and adolescence. She is an experienced pediatrician who has been practicing in the Western Suburbs since 1989.  Dr. Weiss’ Pediatric Residency and Chief Residency training was at the former Children’s Memorial Hospital, now Lurie Children’s Hospital in Chicago, IL.
