and a colleague recommended it. For those who don't have many days off or have fixed days off, I highly recommend this place.
Conveniently located near home...it doesn't take long to get there.
Good service, the doctor and staff are very nice and speak very well.
The doctor took excellent care of my case. The other staff members also provided great advice and showed great care for the patients.
