Help Denzil with Medical and Daily Expenses

Hello. My name is Catherine and my dad Denzil is going through some serious medical issues. Doctors found a few tumors. They are going to do a few biopsies to see what needs to be done. He is either going to have to have open heart surgery or start chemo/radiation depending on the results of biopsies on the tumors. He also has multiple blood clots that they are having to monitor closely. Due to his health issues he hasn't been able to work for a while and is on disability. Mom (Minnie) is currently working for McDonalds, but is having to take some time off to be with Dad while he is going through this. The family appreciates any help that you are able to give. Its very serious and going to be very hard on them with Mom not able to work at this time. Thank you.
