Care philosophy

Medicine isn’t that different from life—you treat people the way you want to be treated. I believe in being knowledgeable and down to earth, so patients understand what’s happening and why. Doctors don’t need to know everything, but they do need to care enough to find the answers. Preventive health is key, and part of my job is helping patients understand their bodies, stay healthy and safe, and learn from past decisions.

When my experience with the Oswego urgent care Dr was horrible and he did not want to do his job or run any tests, My Dr did and there IS something wrong. So Dr Grant always goes above and beyond. I am glad she was available to help me to get to the bottom of my issues.

I felt Judged Honestly. Like I was lacking. Never do I worry my child is not in good hands but I feel uncomfortable when I feel like im being juged for being a working mom. I have to hope and pray that I can get info from my Grandma that my child is doing ok. I ask she says she was good or bad. Thats it. I felt very juged that I was letting my mom bring her into the visit and then joined them from work. I dont appretiate feeling like I am less than because I dont know a few questions.
