About us

Ember Fertility Center | Taj Mahal Medical Center | Laguna Hills, CA

You are the VIP

Welcome to Ember Fertility Center, a state-of-the-art fertility clinic in Laguna Hills, California, that offers our patients a boutique VIP experience while delivering high-tech, evidence-based care. Unwavering in our commitment to serve the diverse Orange County area community, we had the privilege of designing our fertility center with patients as the central focus – from the smallest details to the most involved.

Ember Fertility Center Care Station

Dedicated at every step

You will find this dedication to our patients’ comfort and needs in the physical layout of our aesthetically pleasing facility and, more importantly, in the particular ways we offer our medical and administrative services. Patient consults and treatment appointments are designed with precision to minimize delays and streamline treatment for our patients in all steps of their visit and care.

Ember Fertility Center lab

Expertise & high-tech lab

Our specialists in reproductive medicine are thoroughly trained and highly experienced at developing individualized treatment plans and providing patient guidance and education to choose the right path forward. From our state-of-the-art in vitro fertilization (IVF) and andrology labs with the most sophisticated air filtration to our in-house surgery center, Ember has spared no expense in caring for every detail that impacts a patient’s opportunity for success. This includes our AI-assisted time-lapse embryo incubator that improves IVF outcomes.

Ember Fertility Center’s pledge to our fertility patients

We pledge to provide inclusive fertility services and a dynamic, connected experience through dedication, commitment and focus on each individual. We will know you and your story, because you’re worth it.

  • Our patients are future moms or dads, not case numbers.
  • Fertility treatment or reproductive assistance is a hands-on, guided journey – not an assembly line.
  • Patients enjoy concierge-quality service at every level of care from our responsive and compassionate doctor, medical assistants, nurse practitioners and patient care guides.
  • Ember’s team believes everyone has the right to have a baby. We serve the needs of all couples and individuals with infertility, those in the LGBTQ+ community and others who require reproductive assistance to become parents.

We have a thing for the small things

  • Our world-class clinic offers a welcoming, small-practice atmosphere and is designed for the patient, down to the smallest details that are fine-tuned for success.
  • We serve a smaller number of patients than other clinics so we can focus on quality time and care for each individual.
  • Our fertility doctor pays close attention to the details, and sees the patient at every visit.
  • Our IVF lab takes special care of embryos through the most advanced technology available.
  • We celebrate each little miracle born with Ember’s help.

The right care, the right way

Ember has all the fertility treatments and services patients need under one roof including: all manner of reproductive treatments and technology; an in-house surgery center; and access to egg, embryo and sperm donors and gestational carriers (surrogates).

At Ember, everyone is a VIP – very important patient

And we have a thing for the small things: Each Ember patient gets a dedicated fertility coordinator, a patient’s personal care guide through every clinic detail, from the very first phone call to meeting your little miracle.

The key to our unique patient care is our people

Patient coordinators: personal care guides

Each Ember patient has a dedicated fertility patient coordinator, a patient’s personal care guide – from the initial phone call to the last visit. Much like a VIP’s personal assistant, our patient coordinators get to know each patient and their story, goals, concerns and preferences.

Many Ember coordinators have personal experience with fertility treatments and share their experience with patients, offering empathy and emotional support to forge deeper connections. Educating patients is also a priority for our patient coordinators because we know patients respond better to treatments when they fully understand the issues and options involved.


Ember’s versatile staff is bilingual or trilingual and can converse with patients in English, Chinese, Farsi, Korean, as well as some Spanish and Japanese.
