Lori Case
Nurse Practitioner
I received an associate in arts in 2012 and an associate in nursing in 2014 from Copiah Lincoln community college. I then received a Bachelor of Nursing from the University of Mississippi Medical Center in 2019 and went on to receive a Master of Science in Nursing with a specialty in Family Nursing Practice in 2021.

My hobbies include spending time with her family and 2 dogs Nelson and Hank. In my spare time I enjoy going to the beach and spending time outdoors with my family, including hunting and fishing.
I believe medical cannabis is a safer alternative holistic medicine. I believe it’s safer than traditionl medications made of chemicals components made from pharmaceutical companies trying to make a profit; therefore, getting patients hooked on these medicines that are often hard to step away from.

Joanna Nelson
Nurse Practitioner
Originally from New York, I moved to Mississippi in 2020 with my husband Robert, our daughter Alexandra and our son Nicholas. I graduated from Cornell University in Ithaca, NY in 1993 with a dual BA in Psychology and Pre-Medicine. I continued my education at Columbia University, NY NY, then at Regis College, Weston, MA, graduating in 1999 with my master’s in nursing followed by my Board Certification as a Family Nurse Practitioner with the ANCC.
Throughout my 25-year career as a Nurse Practitioner, I worked primarily in Neurosurgery, treating patients from the ER, the OR, the ICU, and the Clinic Milieu. I also worked 8 years in Addiction Medicine, treating patients from both a Psychiatric and Medical model of care. I believe my work in these two fields of medicine has guided me to the care of the Medical Cannabis patient. My professional drive to help patients has led me to the belief that Medical Cannabis not only improves patient quality of life but goes beyond to alleviate medical conditions such as chronic pain, to mitigate the emotional and physical harm of PTSD and Sleep Disorder, and to work as adjunct therapy to improve the devastating effects of Neurologic Disorders such as Seizure Disorder and Parkinson’s disease.
When not working, I enjoy being my kids’ biggest fan. My daughter Alexandra is an ER nurse in Boston, MA and my son Nicholas is a sophomore at Madison Ridgeland Academy where he is a Varsity Football Offensive Lineman (and a budding Neurosurgeon). I also am Mom to my rescue Pitties, Kyle and Regina George.
Additionally, I love music (trying to teach myself electric guitar) and cooking for my crew.

Rachael Flynn
Nurse Practitinoer
With over 19 years of healthcare experience, I have cultivated a deep-seated desire to improve patient well-being through innovative and empathetic care. My tenure as a registered nurse has allowed me to gain expertise in diverse care settings, including home health, assisted living, and long-term care facilities. These experiences have provided me with a comprehensive understanding of patient needs across various stages of life. I have also witnessed firsthand the limitations of conventional medicine, particularly in managing chronic conditions and pain, which has driven my passion for holistic approaches, including medical cannabis. My goal is to provide patient-centered care that not only treats symptoms but enhances quality of life.
My educational background includes an Associate Degree in Applied Science in Nursing (A.A.S.) at Tulsa Community College, Bachelor of Science in Nursing (B.S.N.) at Southern Nazarene University, 2019- Master of Business Administration (M.B.A.) at Southern Nazarene University, 2024 Master of Science in Nursing (M.S.N.) at Mississippi University for Women
Outside of my professional life, I am passionate about gardening, traveling, and reading. I also enjoy playing online games, which provides a fun way to unwind and connect with others. I find joy in being outdoors, whether tending to my garden or exploring new destinations. Spending time with my husband, children, and animals is incredibly important to me, and we often enjoy outdoor activities together. My love for nature, adventure, and gaming fuels my curiosity and keeps me balanced, while reading allows me to learn and grow continually.
Why I am passionate about cannabis as medicine – I am drawn to the opportunity to educate patients and the broader community about the benefits of medical cannabis. There is a profound need to dismantle the stigma associated with cannabis use, which persists despite substantial scientific evidence supporting its therapeutic benefits. As a healthcare provider, I feel responsible for advocating for patient access to all effective treatments, including medical cannabis, and ensuring they are used safely and responsibly.
