Operations Team


Michelle Hsing Managing Director

With a profound interest and pull toward the fields of science and medicine, and double degrees in both Chemistry and Psychology from University of California, Michelle became an integral part of the Reproductive Fertility Center (RFC) team in 2010.

Her leadership skills, evident in her various roles at RFC, have been in development since her years in college, where she was actively involved in campus organizations, held student-body leadership positions, and gained managerial work experiences.  Being able to fulfill such a vast array of leadership roles, and continuing to succeed in field of fertility, have provided Michelle the skills that make up the foundation of her sound and undeterred professionalism and managerial capabilities.

Born in Taiwan, but raised in the United States, Michelle has the best of all worlds in understanding the cultural differences between the two countries, and is able to bridge the nuances of each culture by demonstrating confidence in her ability to meet with, talk to, and educate both American and Chinese/Non-American patients.  She shares, “exposure to both culture differences have helped me become more sensitive and accepting of other cultures.”

In describing what she enjoys most about the field of reproductive medicine, Michelle recalls the joy and pivotal moments when she realized how much she loved her job as the time she was able to witness the joy and relief displayed by a newly pregnant couple at hearing the heartbeat of their baby for the first time during their first ultrasound visit.

When not making dreams of family come true at RFC, Michelle is the proud “mom” of her six-year-old Dachshund, Mr. Bentley Wang.  She enjoys spending time with her family, friends, and dog, and on some weekends, lounging at home with family and friends watching drama marathons.


Janelle Chun, LVN Assistant to Managing Director

Coming from the service industry, Janelle Chun brought the skills needed to work with people from all walks of life. Her role at Reproductive Fertility Center (RFC) reflects that capacity and is what has made Janelle an indispensable asset to the team.

In transitioning to the infertility field, Janelle applied the philosophy that “everyone has a story” and that the journey to having a family allows the RFC team to become part of that story for their patients. With her natural inclination to liking people, Janelle emits this joy and care in her daily interactions both with co-workers and especially with her patients. A reflection of her infectious care is evident in the friendships and relationships that she develops with those that she comes in contact with, whether in her personal life or work life. Janelle was bestowed the highest honor when a patient named her daughter after Janelle as a result of their blossoming relationship.

As is true with medical technology, infertility is limited by yet-to-be-discovered scientific advances and a guarantee of successful pregnancy for all that seek it is not always feasible. This leaves Janelle burdened by the greatest challenge in infertility treatment – the unsuccessful attempts at biological conception. Some patients are able to seek alternatives to carrying a full-term pregnancy or allow for the assistance of surrogacy. However, limited by religious or cultural restrictions, some patients opt to end their treatment when the course yields continual negative results from the use of their own egg and sperm. The end of their dream leaves Janelle saddened by their choice.

But the journey does continue for so many others and that is the experience that Janelle sees as the most rewarding. Being included as a member of what feels like a family, she thanks Dr. Lin and Grace for spearheading the sense that they are all in this together – like families are. In a field that is dominated by females, Janelle never imagined “being able to work with so many females and get along so well with each one of them”. Like all families, disagreements exist, but somehow they manage to get passed the moments that challenge them and move on to the core values that make them a true team. Janelle has learned to depend on others to get things done and count on others to help her each and every day, freeing her from feeling that she has to do it all.

Fawn Townsend Office Manager

With more than 15 years experience in the field, Fawn has contributed to helping the Reproductive Fertility Center (RFC) team and its patients who come for infertility treatment- providing excellent patient care with a driven work ethic. Fawn’s role in supporting and providing a kind ear to patients is what yields the positive atmosphere of care and concern at RFC.

Fawn has had the privilege of learning the ins and outs of the infertility field by adapting to various roles such as New Patient Coordinator, Financial & Insurance Coordinator, Marketing and Management.; thus gaining expertise knowledge in RFC operations. She has not only grown professionally, but also continues to grow personally with the life lessons she has acquired here. RFC is proud to have Fawn as the Office Manager overseeing our exceptional staff and patients.

As a single mother of four children, Fawn enjoys spending her time with her kids at the beach.

Jennifer Cook, MA New Patient Coordinator

Currently the Manager and Senior Coordinator for the satellite offices at Reproductive Fertility Center, Jennifer Cook has had the unique opportunity of being one of the first staff members since its inception. With a background as a Medical Assistant, Jennifer entered the infertility field after a series of roles in a variety of other capacities. After graduating in 1987, she began an internship at an Obstetrics/Gynecology office. Shortly thereafter, Jennifer switched gears and entered the field of Geriatrics. She truly loved the chance to work in Geriatrics, but at only 18 years of age, she found that it was difficult to continue in a field where so many of her patients passed away.

An opportunity to return to Obstetrics/Gynecology presented itself to Jennifer and she was finding this to be a better, more suitable fit again. Her skills were utilized in billing, medical, the scheduling of surgeries, cosmetic procedures, perinatology, skin rejuvenation and infertility. As luck would have it, one of the nurse practitioners in the OB/GYN office was launching a fertility program in the office and Jennifer seized the opportunity to team up with the Reproductive Endocrinology and Infertility (REI) specialist to assist in the initial evaluation, testing, workup and IUI cycles for their patients. This new venture was exciting and progressive, making Jennifer extremely comfortable in working with the fertility team and patients.

Challenged by her own infertility issues, Jennifer experienced a difficult time of her own attempting to conceive. With the help and support of the team she worked with, she was able to successfully attain pregnancy and her daughter is now 21 years old.

Jennifer met Dr. James Lin through the work at the OB/GYN office and decided to join his team after 12 years with the former group. She continued to train in the field of fertility and has seen the progression of advances in the treatment of infertility for over 25 years. In her opinion, “it only gets better and better”.

What Jennifer shared as her most memorable experience to date is the invitation she received to see one of RFC’s “miracle” babies born to C-section several years ago. She has maintained contact with the couple that invited her and has watched the baby grow into a beautiful young woman. The field of infertility consists of up and downs – emotionally, financially and physically. But being able to be by the couple’s side, being able to comfort and educate them and simply listening to them during their experience is what gives Jennifer the most gratification. The best part of her role shares Jennifer, “is the ability to see our patient’s family grow”.

Although infertility advances have brought successes to thousands of couples, Jennifer still finds it difficult to reconcile the unexplained reasons why some treatments are successful and others are not. Those that can identify the issues have the opportunity for closure, while those that will never know are left with a void of uncertainty. This is the area of infertility that challenges and perplexes Jennifer the most.

Jennifer sees her life as a being part of the RFC “family” from the very beginning. The trust, compassion and support that RFC has extended to her and her family has been instrumental in being able to continue in the face of adversity. Her unsurpassed devotion to the efforts of bringing joy and fulfillment to the RFC patients stems from the underlying goal that RFC has for all those patients that seek their help. She has fond memories of watching the RFC family children grow and mature into productive, compassionate adults in their own rite.

Jennifer Cook is the proud mother of three children that she shares with her loving husband. Other family members include a Doberman named Diesel, a Chihuahua named Cinnabun, along with two cats named Rascal and Binky, a snake and fish. She enjoys sewing, crafting, going to the movies, being outdoors and sharing time with family and friends.


Clinical Team


Paula Hagen, MA Irvine Senior Coordinator

Coordinating IVF cycles has been Paula Hagen’s role for many years. She brought over 10 years of experience in this capacity when she joined Reproductive Fertility Center (RFC).

Being part of the RFC team has been a wonderful experience for Paula. Her role in helping couples achieve the successes of becoming a “family” has brought her great joy. “To call someone and tell them they are pregnant has to be the best part of my role”, shares Paula. Changing their lives with this uplifting news is what makes her role most gratifying.

The field of reproductive medicine is equal to so many other fields in medicine in that not all attempts at attaining success with treatments is realized. There are challenges and Paula realizes that the phone call to share the wonderful news of successful pregnancy is one side of the coin. There are times when she is not able to make that call to share exciting news with her patients. Even with science and technology allowing for leaps in successes with infertility treatments, the science also reveals the downside of embryos that are less than ideal to use. Having to make the call to her patients to deliver the news of unhealthy embryos is sometimes more difficult than making the call to tell them they are not pregnant. Paula understands that although these challenges are innate to the field of reproductive medicine, she can account for there being successes for many couples.

Being part of the RFC team has been by far Paula’s favorite role in her career. She sees the team more as a family unit than as a group of employees. The support and feelings of care and love felt for each other at RFC is infectious and is felt universally. It is not uncommon to hear patients say, “It’s like a family here”.

Paula fills her “away from work” time with her husband and her boys. She enjoys daily exercise, walking, hiking and travelling. Watching football and baseball is a family pastime that isn’t often missed.   Her current plans include training her family’s new lab to be a therapy dog. Recently she had an opportunity to experience this wonderful gift by therapy dogs when her husband was hospitalized and she would love to pay it forward.


LeahAnne Bruce, MA 3rd Party Coordinator

A valued staff member of the Reproductive Fertility Center team since August 2009, LeahAnne Bruce has been an integral part of the infertility side of Obstetrics and Gynecology for nearly 20 years. As RFC’s 3rd Party Coordinator, LeahAnne handles the challenges innate to bridging infertility and successful pregnancies. Her determination and drive to help couples in their attempts to start families is what makes her a “cheerleader, hand-holder, counselor and medical professional” of stellar caliber. Undeterred by the disappointment that comes with infertility, LeahAnne utilizes her experience and positive outlook in recognizing that her patients come in with the perseverance needed to successfully accomplish the goal of growing their family unit. When asked about the most memorable experiences of her role, LeahAnne shares, “When we are successful in helping patients realize their dream of a new baby, it becomes the most memorable and rewarding part of my job”.

From LeahAnne’s perspective, the most challenging and limiting aspects of the infertility field is the emotional element of the experience. Her patients arrive with hope and fear and it’s her role to encourage them to be optimistic about the outcome that lies ahead. Limitations in science and obtaining 100% success rates is not yet feasible. With the support of LeahAnne and her co-workers, every effort is exhausted in ensuring that the couples leave with the success they seek.

LeahAnne attributes her favorite part of her role as being the ability to work with “the dedicated, upbeat and hardworking staff and doctors at RFC”. She has been able to perform her role at various other centers and recognizes that the doctors and staff at RFC share her own personal goal of striving for the success of achieving successful pregnancies for their patients. The RFC team has taught LeahAnne the value of “teamwork and diversification leading to the excitement and pleasure to come to work each day”.

In her own personal accomplishments, LeahAnne is pleased to share her life with a wonderful husband, three children and 2 grandchildren. As one of ten children in her family, LeahAnne is fulfilled by many happy and fun-filled events and activities. With her own children now grown, she enjoys spending time with her husband doing the things they both enjoy doing together such as traveling (when they can) and going to the movies. LeahAnne enjoys reading and catching up with friends and family whenever possible.
