Please help support Sergio's medical expenses

This is my 23 year old son Sergio.  Sergio has had many ongoing medical issues since the age of 12.  At 12 years old he was diagnosed with 2 types of Leukemia at the same time.  He had a bone marrow transplant which required him to get chemotherapy and full body radiation.  While his body was getting ready for his bone marrow transplant he caught a virus that attacks your brain. The virus caused some brain damage on his left temporal lobe, short term memory loss and caused him to start having seizures.  Since then he has had many seizures and has had a VNS (Vagus Nerve Stimulation) implanted and he is on 3 different types of ant seizure medications.  Even with all of the preventative measures he is still having many seizures. This Friday July 12th doctors will perform surgery on his brain to implant a DBS (Deep Brain Stimulator) along with the VNS he currently has to help control his seizures.  We are currently asking for help to help pay for medical bills for his surgery.  Any amount will help and is greatly appreciated.  I ask that you please continue to keep my son in your prayers and thank you in advance to anyone who can pray or donate to his fund.
