“Dr. Claudine Isaacs took charge of my health issues seriously even before I met her. She diligently studied all my records( radiology & pathology reports, etc,) and acted not only as my oncologist but also became my super general physician! She referred me to a gastroenterologist who expertly removed my polyps. She ordered a bone density test that revealed my osteoporosis and referred me to an endocrinologist who is watching my bone care; and to a vascular surgeon for my spleen. She goes more than an extra mile to make sure I will get a clean bill of health….soon.I’m fortunate to have Dr. Isaacs who is widely known as one of the dream team of cancer doctors. I’m grateful to my son-in-law & daughter who brought us together. Special thanks to Julie Babich who tirelessly helped us with appts., follow-ups, and all & of Terri Harrington and all the helpful & friendly staff. Love, Carmen Miller” – Tom M.
