When you're dealing with a complex health challenge like a blood disorder or a cancer diagnosis, the technical skills of your doctor are only half the battle; you also need a guide who treats you with genuine humanity.

To further serve the diverse community of Brooklyn, Dr. Losev and his team offer consultations in Russian, which helps break down communication barriers and provides peace of mind for families navigating complex medical terms in their native language.
Affiliated with the Perlmutter Cancer Center at NYU Langone, Dr. Losev offers his patients a seamless connection to a massive network of specialists and clinical trials.
