Dr. Laura Esserman

Dr. Laura Esserman

Singing Surgeon

One recent Sunday afternoon, she stood in the large, art-filled kitchen of her house in the Ashbury Heights district of San Francisco, rehearsing the song “Defying Gravity” from the musical “Wicked.” It was a request from a patient.

For nearly two decades, Dr. Esserman has sung to her patients as they go under anesthesia. With enough notice, she takes requests.

“Ask for an aria and I might need a week, but most songs take about 15 minutes to learn,” she said.

“Unlimited. My future is unli-mi-ted,” she sang full-throated in her kitchen, for a visitor.

Then she stopped. “You see, that’s the thing,” she said, her gaze intense enough to double as a Vulcan mind meld. “You have to believe in the possible. The minute you think your future is limited, it is.””

Kevin Korth

Kevin Korth


“My aunt passed away from pancreatic cancer six years ago and I have known several colleagues who have been diagnosed in recent years, so this is a personal subject.  Having an opportunity to contribute in a beautiful way towards the distribution of this innovative treatment feels both cathartic and consequential.”

As an in-demand recitalist and coach, pianist Kevin Korth has collaborated with such legendary artists as Frederica von Stade, Jake Heggie, Suzanne Mentzer, Nadine Sierra, Lise Lindstrom, Robert Mann, Joel Krosnick, Marnie Breckenridge, Nicholas Phan, Deborah Voigt, and Brian Asawa.

Praised by Gramophone for playing that is “superb”, and “full of color and character,” his debut album, Out of the Shadows, a recording of American art song with soprano Lisa Delan and cellist Matt Haimovitz on the Pentatone Classics label was very warmly received.

An interpreter of contemporary work, the album features premieres by Jack Perla, Gordon Getty, and David Garner, in addition to previously unrecorded works by Norman Dello Joio and John Kander. Recent projects include an album of Robinson Jeffers settings by composer Christopher Anderson-Bazzoli with mezzo-soprano Buffy Baggott for the Delos label.

Dr. Sanziana Roman

Dr. Sanziana Roman

Singing Surgeon

“I am singing for HairToStay because I believe in working to improve the quality of life for patients who undergo cancer treatments in any possible way; because every moment counts.”

Sanziana A. Roman, M.D., FACS is Professor of Surgery with a clinical interest in endocrine and minimally invasive surgery, with a focus in thyroid and adrenal diseases, including pediatric and adult endocrine tumors. She is one of few high-volume adrenal surgeons around the country performing posterior retroperitoneoscopic adrenalectomy. She is the author of more than 180 peer-reviewed publications in outcomes analysis, cost-effectiveness/decision analysis, meta-analysis, and survey-based methodologies, as well as stem cell research.
Dr. Roman currently serves as the Director of Learning and Teaching in the Procedural Specialties and the Dean’s Diversity Leader for Leadership Equity and Inclusion in the School of Medicine at UCSF. She has a national and international reputation in endocrine surgery and education, having served as the Co-Director of the Fellowship Programs of the American Association of Endocrine Surgeons, and is an active member of leadership committees of several national academic societies, including the American Association of Endocrine Surgeons, the Association for Academic Surgery and the American Thyroid Association.

Prior to her arrival at UCSF, she was a tenured Professor of Surgery at Duke University, where she served as the Director of the Endocrine Surgery Fellowship Program and the Associate Chief of the Division of Advanced Oncologic and Gastrointestinal Surgery.

Dr. Roman organized a symposium about women in surgery, reported on in the World Journal of Surgery in June 2018. The result was powerful testimonials from women surgeons, from Europe to the United States, from Africa to Australia and Asia, reflecting the culture of the place where their career took place. Despite their cultural differences, they all had in common the struggle to establish themselves in the surgical profession, traditionally a male-dominated field.

From the Opera to the Operating Room
“She may have left behind an opera career to pursue medicine, but endocrine surgeon Sanziana A. Roman, M.D., HS ’99, retains definite ideas about music. For a long, complicated case, she puts on a CD of Mozart, Brahms or the Romanian composer Enescu. For something quick like an appendectomy, disco works. And when everyone’s exhausted, it’s hip-hop.

“Studies have shown that surgeons operate better with music,” says Roman.

While different musical themes suit different cases, one mood runs through all of surgery for Roman: the awe she feels toward the surgeon-patient relationship.

“There is no other specialty that allows you to become so intimate with somebody in such a short time. They entrust their body to you. I think that’s incredible—that you allow somebody to completely anesthetize you and cut you open.”

Roman, emigrated with her parents from Romania to Rockland County, N.Y., in 1984, for political reasons. She was 15. Roman already knew she wanted to be a doctor—or maybe an opera singer. She eventually decided that medicine offered a clearer path to stability and success but has managed to combine both interests.

She majored in music performance at Cornell, and while working toward her medical degree at Columbia, she also studied music at Mannes College of Music in Manhattan. During summers she trained at the Aspen Music Festival and once sang the role of Susanna in Mozart’s The Marriage of Figaro at the Graz Music Festival in Austria. It helps that she speaks five languages fluently.

Roman still retains a little of the diva’s flair. She has been known to wear heels in the operating room and she does not own a white coat. Even on a dress-down day when she’s wearing pants and a tracksuit jacket, she sports eye-popping bright floral clogs. “ Excerpt from Yale Medicine Magazine.

Roman, graces the stage of HairToStay The Diva Way as one of our “Singing Surgeons” and “Doctor Divas.” She has collaborated with Laura Esserman in her musical theater troop including roles in the musical Audacity.
