Collins Surgical Associates has been wonderful in helping me through my emergency surgery.  Dr Tandon and Dr Dasilva are excellent surgeons with many years of surgical experience and they saved my life. If not for them I would not be here to raise my children.  You can expect the highest level of care with Collins Surgical Associates.
