Back to another profile in patient courage! This time we have a dental student who is having difficulty walking and taking her tests.

I am not a federal worker, and I cannot understand the stress that the new administration is creating in our federal employees.

However, I have an answer for Elon Musk. Over the past one week, I saw 49 patients in the clinic. I operated on seven brain tumor patients (five of whom had skull base tumors -- acoustic neuroma, sphenoid wing meningioma, tuberculum sella meningioma and two pituitary adenomas). I did two MVDs (one for Hemifacial spasm and one for trigeminal neuralgia). I placed a vp shunt, and I treated four patients with Gamma Knife stereotactic radiosurgery. I also met with my students to review research projects.

My Boss are My Patients!

I believe that meaning and justification can be found in the care of patients.

I am not a federal worker, and I cannot understand the stress that the new administration is creating in our federal employees. However, I have an answer fo...
