My name is Mabel and I am the Front Office Receptionist. I started with Horizon in June of 2017. My job is to make sure the front office runs smoothly. I answer phones, handle the filing, assist with scheduling, supplies and shopping, among other things. My favorite things in life are watching my daughter play softball, painting, working out, hiking, running and Zumba! I absolutely love working at Horizon and being able to interact with the kiddos!
