Meet Lyndsay Hayes, APNP

Lyndsay has been passionate about improving patient care since she graduated with her first nursing degree and while she continued her education to become a provider. She brings over 17 years of patient centered care. Lyndsay is passionate about health and wellness and has spent the last several years helping patients look and feel their best.

Lyndsay is board certified by both the American Nurses Credentialing Center (Family Nurse Practitioner) and by the Oncology Nursing Certification Corporation (Oncology Certified Nurse).

Lyndsay’s Educational Background

Lyndsay has been passionate about improving patient care since she graduated with her first nursing degree in 2004 from the University of Wisconsin-Milwaukee. After several years of nursing, she realized how much more she had to offer patients and the improvements in patient care that were needed. It is evident throughout her entire career that she is truly patient focused.

In 2011, Lyndsay returned to school and successfully graduated from Indiana State University with her Master’s in Nursing Administration. She then took on a leadership role where she was able to develop and implement improvements in patient care. She spent years educating nurses and staff on the importance of treating the patient in a holistic manner, and not just their disease.

Lyndsay has celebrated many successes in her career, but the most notable was her transformation of a cancer care program for patients diagnosed with cancer and going through treatment. She became Oncology Certified in 2016 and worked hard to improve patient education, quality of cancer care and survivorship. She recognized the importance of health and wellness and the absolute necessity to think creatively when it came to traditional medicine. Lyndsay was recognized for her efforts in patient centered care and led the initiative to expand similar cancer programs statewide.

In 2018 Lyndsay completed her Advanced Practice Nursing program and has spent the last 4 years working in the Aesthetic and Plastic Surgery industry. She is an expert in working with patients and helping them look and feel their best. Lyndsay recognizes the need to shift away from the traditional way we treat patients, and to focus on a more functional and holistic care model.  She has recently started her journey towards certification in Functional Medicine and looks forward to helping her patients achieve their health and wellness goals.

When Lyndsay is not providing patient care, she enjoys spending time with her 3 young children and playing golf with her husband. She also loves to work out and prides herself on living life the way she encourages her patients to.

Nurse Practitioner Kera Schill brings her enthusiasm for health and wellness to WIFM, along with over a decade of experience working in health care. Her desire to help patients understand the underlying reasons behind their symptoms led her to explore functional medicine as a way to provide more comprehensive and personalized care.

Kera’s Educational Background

Kera earned her nurse practitioner degree intending to truly influence and change her patients’ lives. By focusing on the root causes of health issues rather than just treating the symptoms, her work in functional medicine offers an all-encompassing approach to fulfill her mission.

Kera leads by example, practicing the healthy habits she promotes to her patients. This allows her to establish trust and relate to people on a deeper level as she provides them with the best possible care. In the future, Kera plans to enhance her education by completing her certification in functional medicine.

For years, patients have sought Kera’s help when they were dissatisfied with past referrals or treatment plans. Now, she applies the principles of functional medicine to help her patients find the answers they are looking for to live their best lives.
