No problems, there is a very helpful brochure put together by the Dept of Economic Affairs in Zug Called "Zug Doctors & Dentists" complete with all languages spoken.
Hünenberg:
Dr. Urs Hürlimann Dr. Ines Hegglin 041 780 46 93
Dr Hanspeter Kläy 041 78028 88
Seems like your choices and finally I found the pdf link to the whole brochure, which I have a printed version through the IMCZ (International Men's Club of Zug).
