Meet Our Team

Mary Pasache – Patient Coordinator

Mary Pasache is our invaluable Patient Coordinator, having been with the practice since 1994. Mary is extremely experienced, knowledgeable and conversant about all facets of our practice, both surgical and non-surgical.

Mary will schedule your consultation with Dr. Horton or Emily Sespaniak, NP, and will answer your initial questions, getting to know you a little over the phone. Mary can provide you with general information about the procedure(s) you are interested in, an estimate of fees, and additional background information about our practice.

You will meet Mary in person after your consultation. She will provide you with information regarding insurance authorization, a quote for expected fees and a packet that describes the procedure(s) in more detail. Mary schedules all our surgeries and works together with other Physicians’ offices to schedule combined procedures (with Breast Surgeons for mastectomies and immediate breast reconstruction, or OB-GYNs for combined Plastic Surgery and gynecological procedures).

Mary will be your “point person” throughout your surgical planning stages and will schedule your Preoperative Visit a week or two before your surgery date. She is available by phone or email to answer your questions and will accommodate your specific scheduling needs as best as possible. Outside of our office, Mary enjoys physical fitness, is an accomplished triathlete and has an incredible shoe collection! She enjoys spending time with her son, her husband of over 16 years and their four dogs. Contact her directly at: mary@drkarenhorton.com.

Emily McCarthy, RN – Preoperative Nurse Educator, Operating Room & PACU Nurse

“Nurse Emily” has successfully filled some big shoes, taking over for Nurse Mari since her retirement. Originally from Bakersfield, California, Nurse Emily has an undergraduate degree in Public Health from the University of California, Berkeley. She received her Master of Nursing in Clinical Nurse Leadership from Georgetown University in Washington D.C. where she then worked in the operating room. Emily is a perfect fit for our office team! We are calling her “Nurse Emily” to differentiate her from Emily Sespaniak NP, our Aesthetic Nurse Practitioner.

Nurse Emily meets every patient of Dr. Horton at their preoperative visit 1-2 weeks before surgery. With a warm, caring and compassionate bedside manner, Emily provides extensive education about surgical recovery, teaches patients about drains if indicated, reviews postoperative restrictions and prescribes postoperative medications. She is there for you every step of your surgical process.

Emily’s role in our practice is multi-will help take care of patients during their Plastic Surgery procedure, in the recovery room and again at each of their follow up visits. Please help us welcome her to our family! She can be reached directly at nurseemily@drkarenhorton.com.

Rachel Powell, RN – Operating Room Nurse Manager

Born in San Francisco and raised in the Bay Area, Rachel has worked in the Plastic Surgery field for over a decade and has been a Nurse Manager for five years. Rachel is thrilled to return to what made her fall in love with working in the Plastic Surgery field: providing full cycle catered care. This includes getting to know patients from their first consultation, educating and prepping them for surgery, comforting them on their big surgery day, and supporting them during their recovery phases.

When not at work, Rachel loves to spend time with her family, practicing mindfulness, and likes to surround herself with GOOD VIBES!

Rose Natukunda, CSPDT – Lead Scrub Technician

Rose Natukunda has been a Surgical Assistant, Operating Room Scrub Technician and Sterile Processing Department (SPD) expert for twenty years. She loves being in the operating room, setting up for complex procedures, and ensuring that all aspects of the surgical process intraoperatively go smoothly. After surgery, she cleans, sterilizes and processes surgical instruments to ensure we are ready for the next patient.

Born and raised in Uganda, Rose worked and traveled throughout the world before settling in San Francisco. She is experienced in assisting/scrubbing advanced Neurosurgery/Spine surgery, Obstetrics and Gynecological Surgery, Endoscopy, Orthopedic Surgery and of course, Plastic Surgery! Rose met Dr. Horton during the pandemic and they discovered they worked together like long-lost family.

When not at work, Rose likes hiking and watching old movies. It’s the little things that make her smile, like seeing an unexpected red door, fireflies and fireworks. Rose is truly a member of our long-term family and we are so happy she is in the operating room with us! In her words, “#BestWorkFamilyEver.”

Sharron Wong – Insurance Preauthorization and Billing Specialist

Behind the scenes managing our Back Office is Sharron Wong. Sharron is fundamental to our office and has been with the practice since 2002. You may seldom see her, but Sharron lends a hand with each and every patient! Sharron is in charge of billing medical insurance for surgeries, insurance preauthorization, accounts payable/receivable and banking activities.

When not hard at work negotiating with insurance companies on behalf of our patients, Sharron enjoys an active lifestyle, volunteering and teaching at the Embarcadero YMCA, maintaining physical fitness, and enjoying World Champion San Francisco Giants baseball!
