About Our providers
Kristi Lorenc CNP, AFMCP
Functional Medicine Nurse Practitioner | MI · OH
My name is Kristi Lorenc. I am a Family Nurse Practitioner and am Certified in Functional Medicine by the School of Applied Functional Medicine.
After having walked many years in the shoes of someone with a chronic diagnosis and dis-ease, I searched for a different path. A path that was narrow but had more than simply symptom management. I found that path in functional medicine. As I started peeling the onion in my healing journey, I discovered that feeling fantastic was not only obtainable but a reality. I knew that this was something I had an obligation to offer my own patients in the family practice setting that I serve.
I began my formal functional medicine training and implemented the principles in the office setting. I quickly saw excellent results and have countless stories of victory over illness, pain, and suffering. My passion grew as well as my knowledge and experience. Having lived with many of the symptoms my patients experience, I have true compassion for those that feel stuck or hopeless with their physical or mental states. I want to offer hope, healing, and vitality to anyone willing to walk that road less traveled. I work with both males and females from the age of newborn on up, in the state of Ohio and Michigan.
Denise
I have been working with Krist through Rapha Functional Wellness for several months. She has been instrumental in helping me become aware of the food and toxins we put in our bodies every day and the harm they can cause. I love the knowledge I receive from Kristi and the handouts she provides as educational tools on my journey to living a healthier lifestyle. There are many facets to this program and if one does not work then we try another until it does. Kristi is always available to answer any questions and does so in a timely manner. I would highly recommend Kristi and Rapha Functional Wellness to anyone wishing to make a healthy lifestyle change while utilizing a more natural approach.
Stephanie
Kristi was very diligent in getting to know me personally, as well as my health history, and was able to relate to me as a middle aged peri-menopausal woman, employee, wife, mother, etc. She was very thorough in our bi-weekly meetings about why my body reacts to certain foods and gave very good resources and explanation on how to get on a better health journey. I am very grateful for her services.
Amy Altamash, MSN, NP-C, IFMCP
Functional Medicine Nurse Practitioner
Holistic Health & Weight Loss Expert | MI· OH ·CO
I believe that healing is possible for everyone.
As a Family Nurse Practitioner and Certified Functional Medicine Practitioner, I specialize in helping women over 35, families, and children heal naturally by addressing the root causes of their health struggles. With over nine years of experience, I’ve guided countless clients in Ohio, Michigan, and Colorado through personalized wellness plans that focus on hormone balance, gut health, thyroid function, adrenal health, and metabolic restoration.
My Approach to Functional Medicine & Holistic Healing
I take a comprehensive, science-backed approach to wellness. Through advanced functional medicine testing, in-depth assessments, and customized protocols, I help my clients:
✅ Identify the root cause of weight gain, fatigue, hormone imbalances, and digestive issues
✅ Heal the gut and support the microbiome for optimal health
✅ Improve energy levels and reduce chronic stress and adrenal dysfunction
✅ Balance hormones naturally to support metabolism, mood, and overall well-being
✅ Create sustainable, real-food nutrition plans for long-term success
WHO I HELP
I work with clients of all ages, from women struggling with perimenopause and weight loss resistance to children dealing with food sensitivities and gut health issues. Whether you’re looking for one-on-one consultations or a structured group coaching program, I provide the guidance and support you need to heal naturally.
For women 35+ struggling with stubborn weight gain, I offer my 35+ Weight Loss Blueprint, a science-based metabolic reset program that helps you lose weight without fad diets, over-exercising, or calorie restriction.
More Than Just Health—A Lifestyle Approach
When I’m not working with clients, I’m homeschooling my three little ones, growing our own food, cooking from scratch, and embracing a homesteading lifestyle. I understand how busy life can get, which is why my approach to healing is practical, sustainable, and tailored to fit real-life demands.
If you’re searching for a functional medicine expert in Ohio, Michigan, or Colorado who truly listens, sees the whole picture, and provides science-backed, holistic solutions, I’d love to help.
Melissa
I started with Amy several years ago . I was having severe skin rashes which were miserable. I made an appointment to see Amy and she was able to help me heal from the inside out . She is the first person that I have seen that started from the beginning of my issues and from there was able to guide me in the healing process, through diet and supplements.
Mallory
Working with Amy has been hugely helpful in identifying lifestyle and eating patterns that have been unhelpful to me. Pursuing the testing and getting a more complete picture of health has not just helped me form better habits, but also lose weight and improve other issues like fatigue and nausea.
ERIN
Reluctant, nervous, desperate. All words to describe the beginning of my AIP journey. I’m not a stranger to healthy habits, in fact I’m quite passionate about health and wellness. Unfortunately I’ve been better acquainted with stress, 5-6 hours of sleep, under/over eating, chronic headaches and crazy hormones the last 10 years. Life screeched to a halt a few years ago when I was diagnosed with thyroid cancer. My body had enough I suppose. Something needed to change. Now, I could have chose the path that would have me taking numerous medications to combat all my symptoms. I whole heartedly believe the human body is wonderfully and fearfully made with the ability to heal itself in some cases. I’ve chosen instead the long journey of healing my body from the inside out. I’ve been working with Amy for several years and her guidance has helped me realize the accumulation of negative physical and environmental factors will take time but with perseverance can be reversed. I hold onto that hope even now, 3 months into the process. Its been one of the toughest most rewarding things I’ve ever done for myself. I am not just doing this for me, but also for my family because I want to be around for as long as the good Lord wills. The program Amy has developed was everything I needed to stick with it because AIP takes commitment! Rapha Functional Wellness provided a community of support, one on one meetings with Amy, delicious recipes I will continue to make and more importantly relief!! My headaches have improved so much and I attribute that to the elimination of sugar and gluten and all the other junk in processed foods. Amy has also devised a personalized plan to heal my gut with REAL food and supplements for the specific vitamin and minerals deficiencies I’m struggling with. If you’re tired of feeling tired, if you need to make some drastic changes, do this for yourself. Its hard, but you have support and a health professional that will take the time to listen AND communicate back to you. That kind of care is hard to find these days! Amy, thank you for walking alongside me to find joy in life again.
Melanie Dorion MSN,APRN, AGNP-BC
Functional & Precision Medicine Nurse Practitioner | VA · CO · FL · IL
"Feeling great at every age and stage of life is your birthright."
Melanie is a nurse practitioner with over 12 years of clinical experience helping teens, adults, and older adults identify the root causes of chronic illness — and reclaim genuine, lasting health.
Her approach is systems-based and rigorous: blending functional and precision medicine with nutrition therapy, peptides, and IV nutrient support to restore resilience from the inside out. This isn't symptom management. It's ownership of your own health.
Melanie studied naturopathic medicine at Bastyr University, earned her NP from Seattle University, and pursued advanced training in geriatrics, obesity management, nutrigenomics, exercise science, herbal medicine, and genetics. She has presented nationally and internationally for Genova Diagnostics, A4M, and Biohealth Congress, and currently teaches through Pentad Integrative Health and serves as President and Director of Education at Renewed Institute.
As a former professional athlete who personally navigated and reversed advanced chronic disease, she brings both the clinical depth and the lived experience. She knows what it feels like to be dismissed — and she knows what's possible on the other side.
Her focus now: pushing healthcare past "not sick" into genuinely optimal.
WHO I HELP
✅Lyme, tick-borne illness & mold-related conditions — including MAST Cell Activation Syndrome (MCAS) and dysautonomia. This work is intensive; limited spots available.
✅Autoimmune disease — thyroid disorders, connective tissue conditions, MS
✅Bone health — prevention and early intervention for bone loss
✅Brain health & cognitive decline — for those serious about delaying or preventing dementia and Alzheimer's. Best suited for prevention and early-stage support.

✅Performance & optimization — for athletes, active adults, and anyone who wants more from their body and brain
✅Mental health support — depression, anxiety, burnout, cognitive overload, and simply not feeling like yourself. Melanie also collaborates with neurofeedback practitioners who use QEEG brain mapping, integrating precision and functional medicine to address the physiologic, nutritional, metabolic, and inflammatory factors that affect brain function.
K.B. 59yo Life Coach
I had a terrible, roiling stomach, for years. I just assumed, "Well, I'm aging." Then, I got diverticulitis and knew I wanted to avoid surgery. So I went to Melanie and her staff. She coached me through the process to discover how my particular body works. It felt like getting a personalized instruction manual at the age of 60. And now, no more roiling. I feel I have the tools to avoid another bout of diverticulitis. I am grateful and relieved. Thank you.
S. W. 20yo college student athlete
When I started with Be Vital, I was experiencing a plethora of debilitating symptoms that were keeping me from fully enjoying life, especially as a teenager who wants to be out and active! I had seen several other doctors who were unwilling to look any deeper than treating the symptoms and it was frustrating. Melanie and her team helped me to get to the root cause of a lot of my symptoms and were always willing to reassess my situation as it progressed in order
to ensure that my treatment was exactly what I needed. I’m very happy that we came to BeVital Melanie, and I don’t know where I would be in my health journey without them.

lose weight and wow my workouts and energy have been SO much better!
