Specially for Children

My Passion for Healthcare

I was intrigued as a high schooler by the science of medicine and the ability to have a positive and meaningful influence in people's lives. As I pursued a career in medicine, I quickly realized how enjoyable it is to help children and young adults. When I looked at blood under the microscope and had my first interaction with a sick Hematology patient, I knew where I wanted to spend my career.

Services I Provide

  1. Consultation for Blood Abnormalities
  2. Ongoing Care of Chronic Blood Problems
  3. Painless Bone Marrow Aspiration/Biopsy
  4. Outpatient Blood or Platelet Transfusion
  5. IVIG Infusion for ITP

My Clinical Focus

I have extensive experience caring for patients with white blood cell, red blood cell and platelets problems. These problems fall into three general catergories: 1. Too many blood cells or platelets, 2. Too few, or 3. They don't work right. The other general category of patients I care for have an imbalance in their clotting system in which they bleed for longer than usual, known as a bleeding disorder, or they clot too easily.
