About MK Medical Wellness: Stories, Support & Trust
At MK Medical Wellness, we are passionate about making healthcare accessible and affordable for everyone.
Wellness and weight loss products have often been priced out of reach for many. But at MK Medical Wellness, we are committed to changing that by offering wellness and prescription weight loss products at a fraction of the traditional cost. I have personally used these products and successfully lost over 75 pounds with prescription medication. After thorough research, my team and I have created a portfolio of high-quality medications designed to support you on your wellness and weight loss journey, with a personalized approach. With real life experience using these medications, I am confident in helping you achieve your weight loss goals.
Our mission is to provide you with the tools needed to create healthy and sustainable habits. We focus on treating the whole picture of your health, not just the number on the scale. In addition to prescribing Semaglutide for weight loss, we also offer a supplementation protocol that supports your body individually throughout the process.
While these supplements are optional, we highly recommend them. We believe that exercise plays an essential role in a successful weight loss journey. We’ll work closely with you to develop a personalized plan, combining Semaglutide with a tailored exercise regimen to help you reach your goals.
We understand that prescription weight loss can be a financial commitment, so we’re proud to offer most prescription medications for under $250 per month. In comparison, brand-name prescriptions like Wegovy or Ozempic typically cost $1,000 to $1,600 per month. Please note that MK Medical Wellness operates on an “out-of-pocket” basis, and we do not bill insurance. However, you may submit your receipt to your insurance provider for possible reimbursement.
Dr. Mary Kate Friess, DNP, FNP-BC
Cofounder, MK Medical Wellness
Dr. Mary Kate Friess has spent over 30 years in healthcare helping patients identify the root causes of their pain, guiding them toward wellness, and empowering them to become the best versions of themselves. As a board-certified family nurse practitioner and clinical leader, she has become a trusted advisor in both primary care and integrative wellness. After witnessing the barriers patients often face in accessing effective, affordable weight loss and wellness solutions, she was driven to create a new model of care. With that mission in mind, MK Medical Wellness was born.
In her pursuit of clinical excellence as a family nurse practitioner and psychiatric mental health nurse practitioner for over 22 years and a registered nurse for 10 years, Dr. Friess has made lifelong learning a cornerstone of her practice. She holds a Doctor of Nursing Practice (DNP) from Saint Louis University, a Master of Science in Nursing-Family Nurse Practitioner (MSN-FNP) from Concordia University-Wisconsin, another MSN in psychiatric mental health nurse practitioner from Johns Hopkins University, and a Bachelor of Science in Nursing from Marquette University. She also served for over a decade as a professor and NP program director, mentoring the next generation of nurse practitioners.
Mary Kate is a proud wife and mom of four. Between raising her children, running a large geriatric primary care business supporting seniors across the state of Wisconsin, and earning multiple advanced degrees, she often put herself last. Like many of her clients, she understands the frustration of trying everything and still struggling with weight loss. That was part of her motivation for launching MK Medical Wellness and is also why she became a client of herself. To date, she has lost 85 pounds using the very protocols she recommends to others.
Outside of work, Mary Kate loves hosting Sunday dinners with her family, exploring local farmers' markets, planning home renovations, and going on road trips, especially to explore charming towns on the East Coast and Midwest. She is passionate about women’s empowerment, functional medicine, and helping people feel confident in their own skin at every stage of life. Her favorite self-care routines include sauna sessions, cold plunges, and early morning walks with her springer spaniels, Daisy and Lucy.
What’s helped her most on her weight loss journey is pairing GLP-1 medications with the MK Metabolism Support Bundle, which includes medical-grade berberine, protein powder, hydration electrolyte packets, and B12 plus MIC injections. She credits this combination with not only accelerating fat loss but also improving energy, mental clarity, and gut health.

Jodi Navis, RN, BSN
Cofounder, MK Medical Wellness
As a Registered Nurse with a bachelor’s degree in nursing, Jodi Navis has worked in healthcare for over two decades. Her passion for providing effective and affordable wellness products and solutions started when she ran a successful massage therapy business. Jodi’s desire to help her massage clients, not just holistically but also medically, led her to pursue her nursing degrees. She leaped into earning her degrees from Moraine Park Technical College and Walden University with such dedication that she graduated with honors from both programs.
Jodi is a busy mom of three and a new grandma. She enjoys spending time with friends and family, outdoor music venues in the summer, traveling anytime of the year. She stays busy helping her 26-year-old daughter with her 10-month-old grandson, helping her son plan his wedding in June 2026 and keeping up with the crazy schedule of a 14-year-old daughter that is involved in three sports and numerous clubs.
Always active, she exercises on a regular basis and has even completed a half marathon. After training with a certified trainer and following a very strict meal plan for months, Jodi decided that she needed more help to shed the additional 10 pounds that would not disappear and became a client herself in March of 2024. By July that same year, she lost those last stubborn 10 pounds.
Her favorite product is PeptideVite.
