I was a long time patient of Dr DeSilva. Last August I went to him with a lump in my neck that developed overnight. He thought I had an infection and prescribed a Z-pak (which is the standard of care). When I returned twice over the next 3 weeks with no improvement, he basically shamed me out of the office and said be patient. I requested an ENT consult and learned it was Stage-4, metastatic tonsil cancer. By not trusting him, my Drs tell me I saved my own life. Cant recommend him at all.
I have had two recent experiences with Dr. Desilva. Recently he was rude and condescending during a recent physical for my daughter. He showed little respect for any of my concerns about my daughter. The second experience involves him charging for routine immunizations for my son for a physical upfront that are covered by medical plan. According to my provider he should not be charging for these immunizations.

OMG...the guy was overtly hostile towards me from the very second he sat down after entering the room. Then he preceded to bitterly ask, Why are you here; aren't you Dr. Bilan's patient? I explained how she was out of town and the office made the appointment to him instead. Then he bitterly questioned, Why do I have to sit here and listen to your story? Finally he told me to he couldn't help me, to go see Dr. Bilan, and that I was wasting his time. We almost came to blows.

Dr Desilva apparently knew a member of my family and took me off of some medications I was on for depression and anxiety cold turkey, stating he didn't want to get in trouble with this family member. SUCH a conflict of interest, and I have had other members of my family experience the same thing in my family. It would have been better to have chosen to just not see me as a patient rather than take me off of necessary medications.
