The Optimal IV Team
FOUNDER & OWNER
Roxy Selzer
Roxy is a BSN-RN in her 7th year of nursing with a wide range of professional medical experience including working as a Phlebotomist, making her highly proficient and experienced in placing IVs.
After Phlebotomy, Roxy became a Certified Surgical Technician where she worked with a private plastic surgeon's office for 3 years. The experience she gained here has followed her throughout her nursing career, which started when she graduated from Cumberland University in 2017. After working in the ICU caring for Cardiac, Medical, and Neuro ICU patients, Roxy then transferred to the OR and trained in Vascular, General, Robotics, Ortho Trauma, General Trauma, Plastics, Podiatry, Transplants, and Cardiothoracic surgery. She spent just under 4 years as a travel RN, which challenged her to become the exceptional nurse she is today.
Roxy founded Optimal IV Hydration and Wellness out of a desire to help her local community be proactive in their health. After experiencing a potentially life-saving IV Hydration Clinic experience (ask her about it and she’ll give you the details), Roxy realized the importance of a safe and comfortable space to ask questions and have an informative conversation without judgment, which is exactly the environment she strives to create at Optimal IV.
Roxy is also the main caretaker for her 100 year-old-grandfather, who is a wealth of history! In her downtime, she loves to travel with her husband and spend time with her two Great Danes, Rogan and Pearl.

She then trained in Phlebotomy in 1977 and began her career as a Phlebotomist. While working as a Phlebotomist, she trained nursing students on how to draw blood and place IVs. She eventually got married and was a stay-at-home mom to raise her two girls, the joys of her life.
She went back to school and became an LPN in 2008 where she worked as a MedSurg nurse for over 7 years. During this time she went back to school and completed her Associates of Nursing Degree. She finished out her RN career working in Hospice and the VA.
Throughout her career, educating patients and families has been a major highlight and joy. In her words, “I treasure the time I was able to be there for patients and families in their last moments. Being able to help educate and put them at ease in some of the hardest times of their lives will stay with me forever.” She decided to retire when her first grandbaby was born. She has since been enjoying her time at Mimi with two grandbabies. She is excited to come out of retirement part-time to work with Optimal IV Hydration and Wellness clients to educate and make a difference.
