IFM Certified Family Nurse Practitioner

Melanie Kelsey, PA-C

Board Certified Physician Assistant

Melanie, a Florida native, is a board-certified PA with prescriptive authority in the state of Texas.  She grew up as a competitive gymnast, which is how her fascination for the human body began.


Her enthusiasm for functional medicine comes from her own personal health story. She was first exposed to the field of Integrative & Functional Medicine in 2014 while training in PA school. At the time, she personally saw how lifestyle changes could help heal the gut and regulate hormones.  It’s now her life mission to help others become the best version of themselves by identifying the root cause of their illness and working toward optimal health. She feels comfortable with complex cases and will work with your specialists and outside practitioners as needed.


Melanie earned her undergraduate degree at the University of Florida with a Bachelor of Science degree in Applied Physiology and Kinesiology. She achieved her Master of Physician Assistant Studies at Northeastern University in Boston, Massachusetts. Melanie practiced surgical medicine for 4 years, with broad exposure to OBGYN, stem cell donation, orthopedics, and oncology. Because of her experience, she sees the value and necessity of Western Medicine.


Her eyes opened to the healing powers of functional medicine after mold exposure led her to a health crisis in 2019. Melanie exhausted western medicine without relief, so she began searching for answers. In the end, functional medicine led her towards healing and symptom improvement.


In early 2020, she began formally training in functional medicine through the Institute for Functional Medicine, CellCore Biosciences, and the Medical Academy in Pediatric Special Needs. She has been working exclusively in functional medicine since 2021 and has found great joy in seeing her patients recover! She is dedicated to furthering her education and staying up to date on the latest research and recommendations.


Melanie believes that healing is a journey and is a combination of physical, mental, and spiritual health. She feels honored to join the Alive + Well team and is dedicated to partner with you and our team of healers to help you toward your health goals!

Svetlana Lisovskiy PA-C

Certified Physician Assistant - Pediatrics

Continuing a family tradition of medicine, Svetlana knew she wanted to be a physician at the age of 13. She’s passionate and dedicated to the health and healing of her patients, with her main goal as finding the root-cause. First, she treats the symptoms for her patients to gain relief, then Svetlana works forensically to find the root cause. Her discoveries lead her patients to heal from within and achieve long-lasting results.
Svetlana earned her MD degree from the distinguished 2nd Moscow State School of Medicine in 1986. She then practiced as a general pediatrician and later specialized in pediatric hematology. After that, she worked at Moscow Regional Hemophilia Clinic for three years. After an impressive tenure, Svetlana then immigrated from the Soviet Union to California where she earned her Physician Assistant Master’s degree from Samuel Merritt College in 2006. Svetlana then saw patients in an endocrinology/internal medicine practice while also conducting clinical trials as a co-investigator. In 2017, Svetlana discovered functional medicine as an alternative approach to providing comprehensive diagnostic and treatment care to patients. Svetlana has dedicated her time to learning functional medicine ever since. In 2018, she achieved the status of Functional Medicine Provider from the University of Functional Medicine.
The functional medicine field showed her how to treat the body as a complex system and tackle the root-cause instead of focusing solely on symptoms. Her special interests include Lyme disease and genetics predisposing patients to chronic conditions. She is ILDADS (International Lyme and Associated Disorders Society) trained provider.

The combination of her knowledge of western medicine and functional medicine allows her to better understand the root cause and gain greater healing. In March 2021, she moved to Austin to join the team at Oubre Medical, which merged with Root Causes Medical Clinic in early 2022, and now is Alive and Well. Working at this unique practice has brought complete professional satisfaction to Svetlana, and she enjoys collaborative teamwork.


Elise Clark, FNP

Family Nurse Practitioner

Born and raised in the DFW area, Elise is a native-Texan Family Nurse Practitioner (FNP). After graduating with Honors and obtaining a Bachelor of Nursing from University of Texas, Austin, Elise worked alongside an OBGYN. That opportunity sparked an interest in hormones’ effect on the body, so she continued her education at Texas Women’s University.

Once again thriving and graduating with Honors, Elise achieved her Master of Science in Nursing in 2015. She then started her career as a Certified Family Nurse Practitioner in family practice, then endocrinology. 

After practicing as an NP in a traditional setting for some time, she realized there was more she could do for her patients. Her realization led her to functional medicine. Elise has now been working in functional medicine for six years. She loves how she can see the difference that personalized medicine makes for her patients.

Elise is certified in Advanced Hormone Replacement Therapy from Worldlink Medical and is a certified Family Nurse Practitioner through the American Academy of Nurse Practitioners. Her interests and areas of expertise include hormone replacement therapy for men and women of all ages, PCOS, thyroid disorders, exercise and nutrition as medicine, gut health, and nutritional deficiencies.

In her spare time, Elise enjoys yoga, reading, and spending time with her husband and young son.

He further solidified his expertise by obtaining certification through the ANCC.

During his tenure at UPMC Pinnacle, where he initially worked in urgent care before transitioning to family practice, Daniel developed a keen interest in integrative approaches to medicine. He has dedicated himself to integrative medicine, focusing on personalized treatment plans that incorporate  nutraceuticals, essential oils, peptides and IV therapies.

Daniel’s dedication extends beyond his professional pursuits. He is deeply committed to his patients’ well-being, taking the time to listen and understand their concerns. Always believing that everyone has knowledge to offer.

Outside of his practice, Daniel finds joy in spending time with his family, especially playing with his children, and traveling. If given the choice, he would spend countless hours soaking up the sun at the beach, a place where he finds peace and relaxation.

Jenny Cohodes

Health Coach

Jenny Cohodes, resides in Austin, Texas, where she serves as a Certified Health and Nutrition Coach. Her personal experiences with food sensitivities, mold, Lyme, EBV, and more have ignited a passion within her to guide others through similar challenges on their wellness paths. Beyond aiding those dealing with chronic illness, Jenny is also passionate about educating individuals on optimizing their health using the latest holistic methods available.
Originally trained as an elementary teacher at the University of Texas at Austin, Jenny’s career path took an unexpected turn when she decided to leave teaching to pursue her newfound passion for nutrition and holistic health. Through countless hours of research, experimentation, and self-education, Jenny honed her culinary skills and developed a keen understanding of the connection between diet and well-being.
Driven by her desire to make a meaningful difference in people’s lives, Jenny furthered her education by obtaining certification in health and nutrition coaching from Precision Nutrition and began leading groups of people through health coaching containers to help them eat, move, and live better lives.    Beyond mere dietary guidance, Jenny loves delving into topics such as nervous system regulation, self-care practices, and cultivating a holistic approach to wellness.
However, Jenny’s journey took an unexpected turn in 2022 when she discovered her own health challenges. Living in a mold-infested environment, she experienced a myriad of symptoms, including the reactivation of a dormant Lyme disease and EBV.  Undeterred by adversity, Jenny embarked on a journey of healing, immersing herself in research and adopting detoxification practices to support her body’s recovery.
Today, Jenny approaches her work with empathy, compassion, and a deep understanding of the profound impact that nutrition and lifestyle choices can have on overall well-being. Outside of her professional sphere, she immerses herself in cooking, developing new recipes, hiking, and exploring new destinations alongside her husband, Dave, and their three children: Madison, Max, and Maverick.
