Our Core Team

Vivien Liu

Founder & CEO

Vivien is the heartbeat of the company. As a Cambridge graduate coming from a luxury brand management background with Harrods, Prada and LVMH, Vivien brings in the highest level of customer service and brand experience to all her endeavors. Having to sacrifice her decade-long promising career to fulfill parenthood dreams lent her the hard-won joy as a mother. It also fostered her compassion towards others who are fighting to build their own families.

Vivien formed Giving Tree on the belief that planned parenthood is a journey where selfless people work together to make miracles happen and care must run through it consistently before, during and after any surrogacy pregnancies.

"I love working in the surrogacy and egg donation industry, because it is a battlefield where vision, execution and ethical standards are demanded and challenged to its core. It is also a cradle where life and hope are created with care, perseverance, and love. What more do you want?"

“For me being able to do even the smallest thing to help people makes me happy, that’s why
since the day I started in Giving Tree Surrogacy I felt that I was making a difference. I am really
grateful to my team for welcoming me with open arms and making me feel part of it since day

Tracey Lujan

Case Manager

Tracey is new to the world of surrogacy. Her journey began working in child protective services. Naturally, she transitioned into working with members of the community that have mental illness and developmental disabilities. Through the process of navigating extremely stressful situations and helping individuals find their voice, Tracey found her passion and what she believes in. This work led her to prioritizing long term change. She stepped into the foster system with the intention of helping children and families who were most vulnerable. Thankfully, she had been blessed again, with the opportunity to bring smiles to families through surrogacy. Tracey looks forward to being a part of the journey of growing families. She believes her calm, supportive demeanor will assist in building trusting relationships. In her spare time she enjoys crafting and painting; however, her most favorite thing to do is spend time with family and watch her granddaughter grow.

"Nothing is more gratifying than guiding others to achieve their goals, while encouraging them to find happiness through their journey."

Because of this experience, she understands and empathizes with those families who can't conceive and carry children on their own due to various reasons. Esther wants to use her work experience and her passion and love to help families fulfill their aspirations.
