Marciniec, FNP-BC
Experience
I began my healthcare journey after earning my nursing degree from Purdue University in 2003. For more than a decade, I worked in the fast-paced environment of the ER at Methodist Hospital, caring for patients during some of their most critical moments. While I valued that work, I felt a deep calling to do more than treat illness—I wanted to help people prevent it.
That calling led me back to school to earn my Master’s degree and eventually into the world of functional medicine. Frustrated by how often traditional medicine failed to truly restore health, I began training with The Institute for Functional Medicine (IFM) in 2015, later adding advanced education through the American Academy for Anti-Aging Medicine (A4M). I spent the next six years practicing in a clinic that blended functional and conventional medicine, helping patients find the root causes of their symptoms and guiding them toward lasting wellness.
Alongside my work in functional medicine, I developed a passion for aesthetics—helping men and women look as vibrant as they feel. Over the past eight years, I have completed hundreds of hours of advanced aesthetics training to deliver natural, confidence-boosting results.
In 2023, my husband, Mike Marciniec, NP, and I founded Solid Wellness and Aesthetics to bring together two things we care deeply about—evidence-based functional medicine and natural, personalized aesthetics. Our mission is simple: help people look and feel their absolute best, inside and out.
Personal
Aside from my work as an NP, I am an active member of the Westfield community, where I have 3 fantastic (and busy) kiddos. You may have seen me at the baseball diamonds, soccer fields, wrestling meets, and football games!
I enjoy being with my family, watching and coaching my kids' sports, weightlifting, and soaking in the sunshine (with SPF, of course).
My family and I are active in our faith and church and strongly feel that God's guidance has put them in this place to help others.

Experience
I have been in health care for over the past 25 years. My medical career started as an EMT in 1997 while in college at Depauw University. Over the years, my career progressed from 911 Paramedic to a suburban Firefighter Paramedic, then a Flight paramedic. I returned to school for nursing and then became an Emergency Room RN and then a Flight Nurse. I returned to school again and completed my Nurse Practitioner.
I have spent my career taking care of people when they needed it the most. For the past 7 years, I have been a nurse practitioner specializing in orthopedic trauma and intensive care medicine.
These experiences have shaped the practitioner I am today. I have taken care of the sickest of the sick and have developed a special interest in wanting to optimize men's health and preventing illness.
I have been involved in fitness and sports all my life, from playing Division III college football to being active with my family. I continue to enjoy playing sports and elevating my fitness.
Alyssa Barr, FNP
Experience
My healthcare journey began as an ER nurse at Methodist Hospital, where I acquired essential skills in emergency care and gained a great understanding of patient needs. Over the course of my career, I transitioned into the role of a Family Nurse Practitioner after graduating from the University of Indianapolis. I now have more than seven years of experience as a provider.
My professional focus centers on women's health, particularly preventive care, weight loss and menopause management. I am deeply committed to assisting women in navigating this transformative phase of life. Additionally, I am passionate about promoting healthy lifestyles and equipping individuals with evidence-based weight management strategies.
In the field of aesthetics, I offer safe and natural treatments designed to enhance self-confidence.
Outside of work, I enjoy exercise, engaging in various outdoor activities, and cooking. I have two kids that keep me busy with sports and after school activities.
My mission is to educate and empower women, enabling them to lead healthier, happier lives through informed decisions and proactive health management. As a healthcare provider, I am more than just a practitioner; I am a dedicated partner in my patients' journeys toward becoming the best versions of themselves. I am ready to collaborate with you to achieve your health and wellness goals.
