Dr. Gruhl was so kind and compassionate. He knew a lot about my health history. He went over and above to ensure I was comfortable with the procedure and during it. I couldn't recommend him enough. He provided exceptional care.

Only think, felt he kind of blew off my concerns of the dizziness I've been having the last few weeks. But he was friendly and felt like he wanted to help me with moving forward and getting a surgery in the near future

I saw the doctor for five minutes. He came in and said if I want the lump removed, let him know and he'll make arrangements to remove it.

Very little discussion about anything. Only that he thought it may be a cyst.
