Meet the Team
M. Yvonne Karney, MD, FACOG, ABAARM
My PASSION is helping women with fatigue. Why? Because I’ve been there. There was a time when I didn’t even recognize myself. I wasn’t the wife, mother, or friend that I wanted to be. I was just too gosh-darn-tired! I eventually had to close part of my practice because I couldn’t keep up. Nobody could put a name or diagnosis on it but I KNEW something was wrong. I had chronic fatigue from crazy hours and high stress.
Through literally thousands of hours researching and over 80,000 patient encounters, I’ve cracked the code on ENDING fatigue. PLEASE don’t let anyone convince you that your fatigue is normal aging! If you are suffering please GET HELP!
WHAT IF you could heal? How would you show up if you had plenty of energy? What would you do with sharp mental focus and energy to last throughout the ENTIRE day? What if you could ride a bike, walk 18 holes, dance the tango/two-step, or garden and still have something left? What if you could wake up embracing the day rather than hitting the snooze button and planning your next nap? What if you had enough energy for work AND play?
I want to help you get your energy back so you can rock your mission! Look—you were here for a purpose. The world needs YOU to be at your BEST. I want to help you achieve your best-self so that you can be PRESENT and ENJOY your life! It’s time to stop putting yourself on the back burner. TODAY is the first day of the rest of your life.
Shall we get started?
Tanya Tanzillo, DNP, FNP-BC
I have had the pleasure of caring for McHenry County community members for over 20 years. Through searching for the best way to help patients optimize their health, I discovered functional medicine and knew I had found my home! Eventually I obtained my PhD, with my thesis on men’s health.
I love the way functional medicine emphasizes care of the whole person, and recognizes diet, exercise, stress, and sleep as VITAL pillars of health. I truly love the capacity for healing rather than merely suppressing symptoms with umpteen medications!
My PASSION is to help you maximize WELLNESS. This requires working with your body’s amazing ability to heal! Only you can be the captain of your ship on your journey to wellness. I look forward to helping you navigate the waters!
I have been a nurse since 1995 with a background in telemetry and ICU for 10 years before I became a family nurse practitioner. I graduated from NIU with my Master of Science in Nursing (MSN) as a Family Nurse Practitioner (FNP) in 2004. I completed my Doctor of Nursing Practice (DNP) in 2014 from Southern Illinois University.
Charmagne Benz, MS, FNP-BC
I have always dreamed of helping people become the healthiest versions of themselves. I became a nurse for this reason, but over time began to see that the traditional medical model didn’t really make that possible. I worked for 9 years in a hospital setting and then continued my education to become a Family Practice Nurse Practitioner.
During my training at Northern Illinois University, I had the privilege of rotating through Vitality Renewal. I was immediately drawn to functional medicine, and the ability to help people truly heal. I’m so happy to be part of this team!
When I’m not in the office you can find me spending time with my wonderful husband and 3 beautiful boys. Some of my favorite hobbies are being active in my church, being active with my family, playing piano and singing, and doing almost anything outside (especially pickleball)!
Katie Melull, RN and Health Coach
Katie is both a registered nurse and a health coach. She joined the team in the summer of 2019. Katie is passionate about functional medicine and truly enjoys supporting patients on their journey to wellness as a health coach. She is also an expert at IV infusions. Outside of work you will find Katie enjoying time with her husband and young son. She enjoys cooking healthy meals, spending time outdoors, and researching the latest health break-throughs.
Liz Alvarez, MA
Liz joined the Vitality Renewal Team in February, 2022. She is multi-talented. In addition to helping with patient flow she runs the phlebotomy department, administers injections, frequency specific microcurrent and neurofeedback.
Outside of work Liz is a mom to 3 adventurous boys who keep her very busy!
When you meet her you will immediately notice her caring and cheerful personality. So glad to have you on the team Liz!
Cheryl Bakotic, Office Manager
Cheryl is our expert patient-care coordinator and neurofeedback technician. She joined the team October 2018. She spent many years at Good Shepherd and Centegra hospitals as a unit coordinator in several different departments. Immediately prior to joining the Vitality Renewal team she was a Customer Care Specialist for Medela, assisting moms with their breastfeeding needs.
She lives in Spring Grove with her fiance and their two cats. She has 2 grown children—each with their own children, making her a very happy grandma! In her free time Cheryl loves anything outdoors –gardening, kayaking, walking/hiking. And of course—spending time with her grandchildren!
What Cheryl loves about working at Vitality Renewal is the culture in which patients and staff are encouraged and supported to not only grow but to THRIVE! In her own words: “I feel truly blessed and am very excited to be a part of this amazing team.” And we are lucky to have YOU Cheryl!
