“It’s very important to me that we provide individualized and personalized care to our clients. I am committed to making my patients feel comfortable and confident in my care. I treat my patients with sincerity and compassion. I ensure that they have all their questions answered to make sure that they are fully-informed before I present the treatment options that are available and work best for them.”

Dr. Minh N. Ho, M.D., F.A.C.O.G
Medical Director, Reproductive Endocrinologist
Dr. Minh N. Ho, M.D., F.A.C.O.G, is board-certified in Reproductive Endocrinology, Infertility, and OB/GYN of the Coastal Fertility Medical Center. He graduated from medical school more than 30 years ago and has since been demonstrating his skills through practice. Dr. Minh N. Ho is very proficient in treating patients of all backgrounds but specializes in treating patients of Asian descent. His well-known practice and accredited expertise culminated the opportunity for him to provide treatment to elite clientele, including authoritative government officials and high-end celebrities in Vietnam. The majority of his patients travel from China and Vietnam to the United States to receive his infertility treatment, surrogacy and egg donation guidance at the leading full-service IVF medical center, RSMC. Dr. Ho is frequently credited for helping women of all ages with his expertise in advanced maternal age and women’s health.

Dr. Ho came to the US from Vietnam as a refugee in 1979. Within three years, he was accepted into the University of Miami, Miller School of Medicine and graduated with an M.D. in 1986. He then completed a residency in OB/GYN at the world-renowned UT Southwestern Medical Center, Parkland Memorial Hospital, where he invented a patented double-clamp umbilical cord cutter. After completing his residency in 1990, Dr. Ho moved to San Diego and joined the group practice in OB/GYN Kaiser Permanente. To continue his educational endeavors, he later began a fellowship in Reproductive Endocrinology and Infertility at the UC of San Diego, where he worked under the supervision of the Nobel Laureate Candidate, Dr. Samuel Yen. In 1994, with a special grant from the NIH, he served a year as Guest Research Scientist at the internationally recognized National Institutes of Health (NIH) in Bethesda, Maryland and continued to study and prove that granulosa cells express receptors for GnRH. His impressive educational and training background continues to strengthen his expertise in the reproductive sciences field. Throughout his years of practicing medicine, he has helped thousands of couples achieve their dreams of having healthy babies with the gender of choice.

Dr. Ho is well known for serving Asian patients. Although he serves both domestic and international clientele, his cultural understanding of the Asian population provides our international patients the benefit of expert communication. He also specializes in helping patients who are experiencing advanced maternal age and/or endometriosis as well as patients with immunological disorders. Dr. Ho is skilled in finding solutions for advanced maternal age and low ovarian reserve. He enjoys overcoming varied obstacles to fulfill his patient’s dreams.
“I’ve been nicknamed the “nicest gentlemen in the west” because I treat my patients like family. I take a very personal approach to each couple or individual I meet. No patient is alike and neither is their treatment. With customization for every patient, attention to detail is crucial. I want every patient to have the best quality of care and I do everything I can to create a successful outcome. I am not just a physician. I’m also an artist (a musician, poet, and writer). This side of me allows me to treat my patients more with my heart. I like to think it’s a combination of heart, mind, and skill.”
Dr. Ho is very interested in new technologies on the horizon. Specifically, creating embryos from skin cells instead of harvesting as a solution for advanced maternal age. Although still controversial and far in the future, he is also interested in the future of IVF as it relates to gene editing.

She then furthered her education at California State University San Marcos, once again finishing at the top of her class with a 4.0 GPA. Before following her passion of working in her current field of fertility, Annie worked in several medical settings including emergency/urgent care, progressive care, and telemetry.

Annie began her nursing career as an RN in the Progressive Care Unit at Banner Gateway Medical Center. She then had the opportunity to serve as an IVF Coordinator at Bloom Reproductive Institute, where she first developed her interest in fertility. She had grown up locally in Escondido, California with her own close-knit family, and was excited by the idea of helping other families grow. 

She would later go on to spend four years working in the Telemetry department at Palomar Medical Center until she graduated from California State University San Marcos. After graduating, Annie was finally able to pursue her true passion of working as a Nurse Practitioner in the fertility field at Reproductive Sciences Medical Center.

Annie brings a unique blend of technical aptitude, sound decision-making, and emotional intelligence in a patient-focused approach. Always looking to better herself and never taking shortcuts, Annie continually strives to provide the highest level of support to her patients.

As Christina Feist-Heilmeier, RN stated in her book Nurses Are from Heaven, “Every nurse was drawn to nursing because of a desire to care, to serve, or to help.”

Annie not only exemplifies this statement but pushes herself each day to be the best version of herself and exceed her patients’ expectations, providing world-class service and support.

Annie is committed to excellence while delivering high-quality, compassionate, person-centered care.  She has demonstrated the ability to lead by example early in her career and has been recognized several times for her efforts through organizational “top performance” citations including the DAISY award. She is very interested in new research on Platelet-rich plasma (PRP) to stimulate cellular rejuvenation and blood flow, naturally, and potentially enhancing fertility.
