Dr. Marissa Tenenbaum - Plastic Surgeon in Saint Louis, MO

Rigorous Medical Education and Training

Dr. Tenenbaum earned her undergraduate degree in Biomedical Engineering from Washington University in St. Louis, where she graduated summa cum laude, demonstrating an early aptitude for the intricate interplay between engineering principles and human physiology. Her academic journey was distinguished by a series of research projects focused on tissue engineering and biomaterials, culminating in a senior thesis that explored the use of biodegradable scaffolds for facial nerve regeneration. This foundational work earned her multiple honors, including the Dean’s Research Award and a competitive National Science Foundation fellowship, positioning her as a thought leader at the intersection of technology and surgery before she even entered medical school.

Following her undergraduate success, Dr. Tenenbaum pursued her medical degree at the prestigious Washington University School of Medicine, where she distinguished herself as a scholar‑practitioner with a dual focus on clinical excellence and investigative rigor. She completed a series of clerkships that highlighted her aptitude for operative precision, receiving the Outstanding Clinical Performance Award in both the surgical and dermatologic rotations. In parallel, she contributed to groundbreaking clinical trials investigating the efficacy of novel injectable fillers and laser resurfacing modalities, resulting in first‑author publications in high‑impact journals such as *Plastic and Reconstructive Surgery* and *JAMA Dermatology*. Her dedication to academic medicine was further recognized through the Alpha Omega Alpha Honor Medical Society induction and a coveted research grant from the American Society of Plastic Surgeons.

Upon graduating with honors, Dr. Tenenbaum entered a rigorous integrated residency program in plastic and reconstructive surgery at Washington University, a highly selective pathway that combines comprehensive general surgery training with specialized plastic surgery exposure over six years. Throughout her residency, she rotated through high‑volume centers in craniofacial reconstruction, microsurgery, and aesthetic surgery, mastering complex techniques such as free‑flap transfers, facial nerve coaptation, and advanced body contouring. She earned board certification in both Plastic Surgery and Reconstructive Surgery, a testament to her mastery of the full spectrum of operative skills. Her fellowship training at the renowned Mayo Clinic further refined her expertise in aesthetic facial surgery, where she performed over 300 primary rhinoplasties under the mentorship of world‑renowned facial plastic surgeons, solidifying her reputation as a meticulous and innovative surgeon.

Surgical Expertise

In the arena of plastic surgery, Dr. Tenenbaum has cultivated a reputation for delivering outcomes that seamlessly blend artistry with scientific precision. Her portfolio encompasses a broad array of procedures ranging from minimally invasive injectables to complex reconstructive surgeries, each executed with a meticulous attention to detail that reflects her deep understanding of tissue dynamics and wound healing. She has pioneered the use of three‑dimensional imaging and computer‑guided planning in her practice, allowing her to simulate surgical outcomes with unprecedented accuracy and to tailor operative strategies that respect the unique topography of each patient’s anatomy. This technology‑driven approach has been particularly transformative in facial rejuvenation, where subtle adjustments in volume, contour, and skin texture can dramatically enhance natural beauty while preserving facial harmony.

Cosmetic surgery, a domain where patient expectations are heightened and the margin for error is razor‑thin, is a cornerstone of Dr. Tenenbaum’s practice. She routinely performs high‑demand procedures such as abdominoplasty, breast augmentation, and liposuction, integrating advanced techniques like progressive tension sutures, fat grafting, and the use of autologous platelet‑rich plasma to optimize healing and minimize scarring. Her commitment to safety is evident in her rigorous pre‑operative assessments, which include comprehensive cardiovascular and metabolic evaluations to ensure that each patient is an optimal surgical candidate. Moreover, she employs a multimodal analgesia protocol that reduces reliance on opioids, accelerates recovery, and enhances patient satisfaction, reflecting her dedication to evidence‑based peri‑operative care.

Reconstructive surgery, particularly in the context of oncologic and traumatic cases, showcases Dr. Tenenbaum’s capacity to restore both form and function under the most challenging circumstances. She has led multidisciplinary teams in the reconstruction of extensive head and neck defects following tumor resections, employing free‑flap microvascular techniques that restore speech, swallowing, and facial expression. In breast reconstruction, she offers a full spectrum of options—from implant‑based approaches to autologous tissue reconstruction using the DIEP flap—tailoring each plan to the patient’s anatomical considerations, oncologic timeline, and personal preferences. Her innovative use of acellular dermal matrices and regenerative medicine adjuncts has reduced complication rates and improved aesthetic outcomes, positioning her as a leader in the evolution of reconstructive paradigms that prioritize both oncologic safety and quality of life.

Commitment to Patient Safety

Dr. Tenenbaum’s unwavering commitment to patient safety is reflected in her active involvement with premier professional societies that set the gold standard for surgical practice. As a board‑certified member of the American Society of Plastic Surgeons (ASPS), she adheres to the society’s rigorous ethical guidelines, participates in ongoing peer‑reviewed education, and contributes to the development of practice parameters that safeguard patient welfare. Her affiliation with the American College of Surgeons (ACS) further underscores her dedication to surgical excellence, as she regularly engages in the ACS’s Safe Surgery Checklist initiatives and quality improvement programs that aim to reduce peri‑operative morbidity and mortality across all surgical specialties.

At the institutional level, Dr. Tenenbaum has been recognized by the Washington University Faculty Association for her outstanding contributions to clinical excellence. She received the Outstanding Clinical Excellence Award from Washington University School of Medicine, an honor bestowed upon physicians who demonstrate superior patient outcomes, innovative practice patterns, and a culture of mentorship. In addition to these accolades, she has been repeatedly highlighted by *St. Louis Magazine* as a Top Plastic Surgeon, a testament to her reputation within the community for delivering consistently high‑quality care, compassionate patient interaction, and a commitment to continuous improvement. These recognitions are not merely decorative; they reflect a career built upon the pillars of safety, efficacy, and patient‑centered service.

Beyond formal accolades, Dr. Tenenbaum has instituted a comprehensive patient safety framework within her practice that incorporates evidence‑based protocols, real‑time monitoring, and post‑operative surveillance. She employs a robust infection control regimen that includes pre‑operative skin decolonization, intra‑operative antimicrobial irrigation, and postoperative wound care education, resulting in infection rates well below national averages. Her practice also integrates advanced anesthesia monitoring, intra‑operative neuromuscular blockade reversal agents, and postoperative pain management plans that prioritize non‑opioid analgesics. By fostering a culture of transparency, she encourages patients to report any concerns promptly, enabling rapid intervention and continuous quality refinement. This systematic approach to safety has earned her high patient satisfaction scores and a reputation as a surgeon who places the highest priority on the well‑being of those she serves.
