“I practice medicine with compassion, understanding and a little bit of humor. I think most people I care for remember me as a kind person, and that’s very important to me.”

— Leah

What do you enjoy about providing apheresis procedural care?

Patients place a great degree of trust in their health care team and my goal is to support our patients while recognizing that undergoing a procedure can be intimidating and anxiety provoking. Every day, I strive to make a difference for our patients, whether that’s providing physical or emotional/psychological comfort and/or educating patients and families about their disease and treatment plan. I practice medicine with compassion, understanding, and a little bit of humor. I think most people I care for remember me as a kind person, and that’s very important to me.

What personal experiences have informed your approach to care?

My mother is the strongest person I’ve ever known. When she was diagnosed with breast cancer several years ago, it was a very humbling, vulnerable time for the whole family. She’s in remission now, and when I look back on the experience, I think it made me more sensitive to what caregivers go through. Sometimes they can be forgotten in the whole process. I have always believed in a team-oriented approach to medicine, where the patient is the epicenter, and loved ones are also an important part of that team.
