I’m 50 years old, I don’t have extra money to see a doctor or buy asthma medication. St. Mary’s Clinic is a Godsend, I am now able regularly visit a doctor who I can afford, the Clinic helped me find medication to control my asthma. This is the first time in my life that I can take a breath and not wheeze. Thank you for helping me manage and live with asthma.”
