Dr Frentz is the most compassionate doctor I have seen in 30 years. She never rushes through an appointment, and listens carefully to your concerns. She is very knowledgeable and thoroughly explains her diagnosis and proposed treatment.

My husband and I have been patients of Dr. Frentz for many years. When our son was born we trusted no one else to over see his physical well-being. She truly cares for us and when we ask questions she is thorough with her answers. She also doesn't rush through our visits. I know that if we need her we will get answers as quickly as we need them. I recommend her to anyone searching for new doctor because she meets everyone's requirements: Caring, listens, doesn't over treat (doesn't under treat), admits when it's time for a specialist, and is there when needed. Lastly, I am perplexed by any negative review because I have not had a negative experience with her or her staff (or even any other colleagues within the same practice) in the 10 years and counting I have been her patient.

Have been going to Dr. Frentz for several years. Has always been very nice to me,but I do not think she listens to what I am saying. Most the time only focus on my weight and I know I am over weight. I believe she is a very good dr, but needs to listen to her pt. more .

She has been my doctor for a few years now. Went to her for a routine visit and she caught a heart valve sound most doctors miss. She saved my life. A year after my heart valve replacement, I am still here and thriving.

Dr. Frentz has been my doctor for several years now, and I'm extremely pleased with the service I receive from her and from her staff. Even though I know she's busy, she never rushes through my appointments, and always gives me time for questions or concerns. I trust her judgment in the medicines and treatments she prescribes. She is not quick to order medical tests "just in case", but refers me to specialists when it is required. I'm healthier now than when I started seeing her.
