Dr. Sarah Wistreich Asks the Pivotal Questions to Help Patients on Their Journey to Health

“When you have a personal relationship with your patient, you are most able to give that patient effective preventive care.”

Dr. Sarah Wistreich was just 12 years old when she realized her life’s calling to become a doctor. She was inspired by the medical team that saved the life of her younger brother. “Watching the physicians who took care of him as a team really stood out to me,” she says. “It had a big impact on my personal decision.”

She chose family care so that she could treat the full range of ailments. She also enjoys a focus on women’s health. In both cases, Dr. Wistreich works to form meaningful relationships with her patients. “Continuity of care is so important,” she says. “When you know the person, you’re able to meet his or her needs more completely.”

Importantly, Dr. Wistreich asks the pivotal questions. “Are you up to date on your PAP smear? What are you using for birth control? Let’s talk about your weight. What’s going on at home? What is your stress level like?” She emphasizes preventive care, saying to patients, “Let’s talk about taking care of you when you’re well.” Patients enjoy the fact that Dr. Wistreich takes the time to actively listen and understand their concerns. Many women tell her that they enjoy seeing a female physician who can provide PAP smears, breast exams, birth control management, endometrial biopsies and other women’s health services.

Dr. Wistreich chose Vanguard because of its unique approach. “I like that Vanguard really puts the patient first,” she says. “It’s rare that you have a physician group that is owned by its own physicians and not a hospital or network. It’s still a business, but it’s one where the physicians care for the patients first and foremost.”

When she’s not working, Dr. Wistreich enjoys cooking nutritious meals. “Nutrition has become a passion of mine, not only with my patients, but with my family.”

Sarah did a great job. She was professional, knowledgeable, and took quite a bit of time getting to know my situation. For the first time in many years, I feel like I have a true family physician.

Dr W was wonderful. I was a little nervous having to change my primary doctor due to insurance change and I could not have been more pleasantly surprised. She is professional, informative, explained options, decisions and future care. I did not feel rushed or put off. Repeatedly asked if I had questions or concerns and if there was anything else she could do for me.....left feeling really nice about the experience.
