Medicine with Purpose, Experience, and Heart

I am Marsella Jimeno-Peralta, FNP-C, a Board Certified Family Nurse Practitioner, medical doctor by training, and the founder of Aviv by Marsella. My vocation for medicine was not born from a trend or a wellness fad; it was born from real contact with people, deep stories, and bodies that asked to be understood, not just treated.

My Medical Foundations

I graduated as a General Physician in the Dominican Republic in 2005 and practiced for more than 8 years in primary care, accompanying patients through prevention, education, and holistic care. During this time, I was an active participant in television and radio programs, promoting health because I understood early on that educating is also a form of healing.

A Journey of Growth and Balance

Upon moving to the United States and settling in Florida, I made a conscious and deeply human decision: to prioritize my role as a wife and mother without renouncing my professional purpose. I am a wife, a mother to three beautiful teenagers, and a “mom” to four dogs that fill our home with life.

This stage of my life taught me to live with more presence, to listen more deeply, and to understand the vital balance between body, mind, and spirit.

I continued my professional development and became a Board Certified Family Nurse Practitioner (FNP-C). While practicing as an FNP, my medical vision underwent a decisive transformation.

The Path to Functional Medicine

I worked for years in Cardiology, treating patients with complex chronic conditions. However, I noticed a recurring pattern that went beyond the heart: a clear foundation of metabolic and hormonal imbalances at the root of many diseases.

It became evident that many conditions improve, are prevented, or even reversed when weight is optimized, hormones are harmonized, and lifestyle is transformed.

As a Family Nurse Practitioner, I saw women arrive exhausted, inflamed, and struggling with weight gain, insulin resistance, anxiety, and insomnia—symptoms often dismissed as “just part of aging”. When these women received the correct evaluation and a truly personalized plan, the results were powerful:

  • They lost weight safely.
  • They regulated their hormones.
  • They regained energy and mental clarity.
  • They improved their mood and sexual health.
  • They felt in control of their bodies again.

Specialized Expertise

This clinical experience led me to deepen my knowledge through advanced certifications:

  • Weight Management: Working with GLP-1 medications and evidence-based strategies.
  • Female Hormones: Understanding the intricacies of the female endocrine system.
  • Longevity Medicine: Shifting the focus from just living longer to living with total fulfillment and clarity.

My Faith and Purpose

Parallel to my professional growth, I experienced a profound spiritual awakening. Strengthening my faith gave me a clearer understanding of my vocation. I realized that Aviv by Marsella is not a coincidence; it is a way to serve and accompany women as they “be reborn” in a stage of life that is often lived in confusion or silence.

Today, I walk alongside women—especially those in perimenopause and menopause—who are tired of being ignored or minimized and are looking for a professional who will listen, educate, and guide them through their transformation.

“When you understand your biology and honor your process, you regain your power.”

For me, accompanying a woman in her process of being reborn is a privilege.
