She listened to my concerns. She checked with a pharmacist about restarting a medication for me. I am restarting at a low dose as to not have any bad side effects. She explained the reasoning to me.

Jennifer Shimshak is the best. We discuss all my concerns and she is very knowledgeable and helpful. The only problem is that I have to make an appointment a year ahead of time. When health problems come up during the year she will help me with a referral but I can't see her on an ongoing basis. Other people have told me that Internal Medicine is short providers. I wish I could see her for health concerns that come up during the year.

Jennifer Shimshak is an amazing PA and I am so glad that I got a chance to see her. She knows what she's doing. She knows how to care for people. She knows how to explain medical situations. So I thank her for this excellent care.

I have NEVER been to a care provider who listens as well as jennifer does. No matter what the subject she is always well informed. She also does a great job of followup.

Provider was in a hurry to get on with this visit, continually asked "what else" after she answered my question. I felt like this was an oral exam for her. Affect was cold. I/my insurance pays your providers to manage my Healthcare. Its impossible to find an empathetic provider. I feel the Neighborhood Clinics have better personalized care.

I had a great appointment with Jennifer. She really listened to me. We discussed the pros and cons of different treatment options before settling on one. I couldn't have asked for a better experience.

Jennifer was very helpful and knowledgeable; I was unaware there was an option to work with her on understanding glp weight loss medications. Thus, when I messaged my Dr. on mychart, I received a quick response to explain various options. In turn, decided to go a different direction and work with her on moving forward. In turn, my husband is using this option as well. Thank you.

Jennifer Shimshak was amazing. Not only had she reviewed my chart in detail,but she listened to me an I felt she had true sincere empathy for what was going on with me. Having been a social worker in the ER for 30+ years, I felt truly cared for! Thank you.

She was great and finally someone who listened to me. The audio would not work. I couldn't hear her so she called me. Thank goodness!

I highly recommend Jennifer. She took the time to address all my questions and concerns while explaining in a comprehensive manner that was not condescendingly. I felt understood and important.

Jennifer was fabulous: clear, concise, knowledgeable, and also a good listener. (I do think you need a slightly different set of questions for telehealth appointments)

I would rate my primary care physician, Jennifer Shimshak, as a friend, as well as my physician. She is extremely knowledgeable, professional, and I highly recommend her to anyone in need of medical consultation. She has been my support through many trying medical situations.
