About Me

What made you fall in love with your specialty?

I chose oncology during residency and fellowship, after doing rotations, because you get to know the patient well and build relationships with them throughout their cancer journey

Three things people might not know about me

    Dr Hartl is an excellent oncologist. Having had to go through a cancer treatment in 2023 and again now starting in May 2026 and having been treated by 4 different oncologists, per my observations (for what they are worth), Dr Hartl is a superior expert in his field of medicine. However, what really differentiates Dr Hartl from his peers are how he maintains a very calm demeanor, provides and explains the medical condition(s) along with the treatment protocol options in a manner and at a complexity level based on the patient's comprehension ability/level, and the high level of compassion, focus and understanding he shows towards his patient's facing a life threatening/altering health condition.
