CEO & Co-Founder IMA ART Fertility
We specialize in curating bespoke fertility and surrogacy journey's, offering IVF and egg and sperm banking coordination, and legal oversight with absolute discretion," says Michelle Tang, CEO and Co-Founder.
Fertility Governance
Fertility Governance - a risk management framework designed specifically for reproductive planning and execution. It is seen as a structured, centralized oversight of every moving part within the reproductive journey. IMA ART is the only privately held fertility and surrogacy maison that delivers a level of personal stewardship, reserved for those whose time, privacy, and transparent outcomes cannot be compromised.
Our role as a Fertility Family Office includes:
-
Selection and liaison with leading IVF clinics in California, USA
-
Management of IVF timelines, appointments, and communication
-
Embryo creation, cryo-transportation coordination, and genetic testing
-
Surrogate matching, screening, alignment, and monitoring
-
Legal frameworks, drafting and safeguarding parental rights
-
Fertility crisis management and contingency planning
Rather than navigating multiple providers independently, clients experience a single, unified strategy - professionally managed from pre-beginning to outcome.
Private Client Fertility Maison
Founded in Beverly Hills, California, IMA ART provides bespoke fertility advisory, private IVF coordination, and white-glove surrogacy guidance for individuals and couples who value discretion, precision, and exceptional personal stewardship. Unlike an IVF clinic or traditional surrogacy agency, we independently coordinate every stage of the reproductive journey, allowing our clients to move forward with confidence through one trusted point of oversight.
This independent, principal-led model is what we call the world's first Fertility Family Office—a private approach to fertility management that brings together medical specialists, embryologists, reproductive attorneys, psychologists, and surrogacy professionals within a single, coordinated strategy focused on one outcome: helping you build your family with clarity, continuity, and confidence.
For private clients, this means highly personalized guidance from early fertility consultation and clinic selection through embryo strategy, genetic testing coordination, and, where requested, surrogate matching and ongoing journey management. Every recommendation is tailored to your unique medical, personal, and family-building objectives.
Over the years, IMA ART has cultivated relationships with many of the world's leading experts in Assisted Reproductive Technology (ART), reproductive law, clinical psychology, and surrogacy. Our clients benefit from private access to this carefully developed network, supported by independent guidance and founder-led stewardship throughout every stage of their family-building journey.

Private Surrogacy, Personally Stewarded
Surrogacy at IMA ART extends far beyond finding a match. Our principals personally engage with the women we consider as surrogates, remaining closely involved through screening, medical preparation, embryo transfer and the pregnancy journey.
We believe a surrogate is far more than a profile—and that intended parents deserve to know who may carry their child.
IMA ART's Difference
IMA ART is an independent fertility and surrogacy advisory in Beverly Hills, providing principal-led stewardship across complex family-building journeys. Michelle Tang and Ron Sonnenberg remain personally and actively involved throughout each client engagement—accessible seven days a week and present at the moments where their involvement matters most.
Our role extends beyond coordinating individual providers. We advocate for our clients, maintain continuity across medical, legal, psychological and surrogacy professionals, anticipate potential complications and help ensure that important decisions are considered within the context of the journey as a whole.
For clients traveling to California or elsewhere in the United States for treatment, screening or embryo transfer, we coordinate the practical details surrounding their care with the same discretion and attention given to the reproductive journey itself. Travel, accommodation, transportation and other personal arrangements can be managed when required—quietly and without becoming the definition of the service.
Haute Fertility
Haute Fertility is IMA ART's approach to highly individualized fertility and surrogacy stewardship. It is not defined by amenities or appearances, but by the time, judgment and personal involvement devoted to each family-building journey.
IMA ART remains independent of IVF clinics, egg and sperm donor agencies, reproductive law firms and other providers involved in a client's care. This independence allows our principals to evaluate options objectively, coordinate across multiple specialists and advocate solely from the perspective of the client and their family-building objectives.
With a deliberately limited number of engagements at any given time, our principals remain personally involved throughout the journey—providing continuity, discretion and informed guidance as circumstances evolve.
Discreet Fertility Advisory
Privacy in fertility and surrogacy extends beyond confidentiality. For ultra-high-net-worth individuals and private families, it can require careful consideration of who has access to personal information, how communication is managed, which professionals become involved and how sensitive decisions are documented and shared.
IMA ART coordinates each engagement with discretion from the outset, working across fertility clinics, reproductive attorneys, psychologists, surrogacy professionals and other specialists while helping clients maintain appropriate boundaries around their family-building journey.
Where personal, family or professional circumstances require heightened discretion, our principals remain closely involved in determining how information, introductions and communication are managed throughout the process.
Principal-Led Family Creation
At IMA ART, principal-led means more than senior-level availability. Michelle Tang and Ron Sonnenberg remain personally engaged in the decisions, relationships and critical moments that shape each family-building journey.
From the selection and coordination of fertility specialists to surrogate evaluation, reproductive law, psychological support and the practical complexities that arise along the way, our principals maintain continuity across the professionals involved.
This direct involvement allows IMA ART to understand not only where a journey stands, but how it arrived there, what has already been considered and what may require attention next. For clients, that continuity means fewer handoffs, greater context and a relationship that remains personal from beginning to desired outcome.
White-Glove Fertility Concierge
Every fertility and surrogacy journey is different. IMA ART provides a single point of guidance across the medical, legal, psychological and practical considerations involved in building a family.
Our role is not to replace the physicians, attorneys or other specialists responsible for their respective areas of expertise. We help clients identify, coordinate and communicate with those professionals while maintaining continuity across the journey as a whole.
The following seven stages illustrate how IMA ART stewardship may extend from the earliest conversations through treatment, surrogacy and the creation of a family.
Step 1 - Fertility Consultation & Strategy
We begin by understanding where you are in your family-building journey, what has already been explored and what you hope to achieve. From there, we help identify priorities, potential pathways and the specialists who may need to become involved.
Surrogacy at IMA ART extends beyond access to profiles. Our principals remain personally involved in surrogate evaluation and matching, considering medical screening alongside the human factors that can shape a successful relationship between intended parents and the woman who may carry their child.
IMA ART helps clients evaluate and coordinate with reproductive endocrinologists and fertility clinics appropriate to their circumstances. We remain engaged around appointments, communication, treatment timelines and the practical details surrounding care while medical decisions remain with the treating physician.
Step 3 - Embryo Creation & Reproductive Genetics
Where embryo creation forms part of the journey, we help coordinate the specialists, laboratories and decisions involved, including reproductive genetics and embryo testing when clinically appropriate. Our role is to help clients understand the process and maintain continuity across the professionals responsible for their care.
When donor eggs or sperm are required, IMA ART assists with donor-source evaluation, coordination and the medical, legal and psychological considerations surrounding donor conception. The objective is not simply to locate a donor, but to help clients make informed decisions within the context of their broader family-building plans.
Fertility and surrogacy can involve complex legal considerations, particularly when multiple jurisdictions or international families are involved. IMA ART coordinates with experienced reproductive attorneys while helping clients maintain continuity between legal planning and the medical and surrogacy journey.
Step 7 - Pregnancy, Birth & Postpartum
Our involvement does not end with embryo transfer. Throughout a surrogate pregnancy, IMA ART remains engaged with intended parents, the surrogate and the professionals involved, helping coordinate communication, practical needs and preparations for birth. Our stewardship continues through delivery and the immediate postpartum period.

Begin Your Private Fertility Journey.
Every fertility journey begins with different circumstances, priorities and decisions. IMA ART works privately with individuals and families seeking dedicated oversight of IVF, embryo planning, fertility preservation, donor conception and fertility journeys that may ultimately involve surrogacy.
Our involvement begins with understanding where you are today, what you hope to achieve and which medical or other professionals may already be involved. From there, we can determine where IMA ART's coordination, personal involvement and broader fertility oversight can add value to your journey.
IMA ART Fertility is based in Beverly Hills, California, and works with private clients throughout the United States and internationally.
What is White-Glove Fertility?
White-glove fertility is a highly personalized approach to fertility care in which the experienced principals of IMA ART coordinate the medical, legal, psychological and practical elements surrounding treatment and a seamless journey to parenthood.
At IMA ART, white-glove fertility means deliberately limiting the number of clients we engage, providing direct access to our principals and maintaining continuity across the specialists involved in each journey. Medical diagnosis and treatment remain with the reproductive endocrinologist and fertility clinic; IMA ART provides independent guidance, coordination and advocacy around the journey as a whole.
How is IMA ART different from a traditional surrogacy agency?
IMA ART is an independent fertility and surrogacy advisory based in Beverly Hills, California. Unlike a traditional surrogacy agency focused primarily on recruiting and matching intended parents with a surrogate, IMA ART can remain involved across the broader family-building journey.
Our work may include IVF coordination, embryo strategy, surrogate selection and matching, reproductive law, psychological support, insurance, pregnancy coordination and birth planning. Michelle Tang and Ron Sonnenberg remain personally engaged throughout each client relationship, providing continuity across the professionals and decisions involved.
What is gestational surrogacy?
Gestational surrogacy is a form of family building in which a surrogate carries an embryo created through in vitro fertilization (IVF) and has no genetic relationship to the child she is carrying. The embryo may be created using the intended parents' eggs and sperm or with the assistance of an egg donor or sperm donor.
IMA ART specializes in gestational surrogacy, coordinating the surrogate journey alongside fertility clinics, reproductive attorneys, psychologists, insurance professionals and other specialists involved in helping intended parents build their families.
How much does surrogacy cost in the United States?
The total cost of surrogacy in the United States varies considerably according to the circumstances of each journey. Expenses can include surrogate compensation and allowances, IVF and fertility clinic costs, medical screening, legal representation, escrow, insurance, psychological support, travel and professional surrogacy fees.
Costs can also change if additional embryo transfers, medical care or other unforeseen circumstances arise. IMA ART helps clients understand and coordinate the financial components of a surrogacy journey from the outset so that decisions are considered within the context of the journey as a whole.
How does the surrogate matching process work?
Surrogate matching involves identifying a potential gestational surrogate whose medical eligibility, personal circumstances, expectations and preferences are compatible with those of the intended parents.
At IMA ART, surrogate selection extends beyond access to a profile. Candidates undergo medical, psychological and other appropriate screening, while our principals personally engage with prospective surrogates as part of the evaluation and matching process. We consider not only whether a surrogate can carry a pregnancy, but whether the relationship between the surrogate and intended parents has the foundation for a successful journey.
Who does IMA ART work with?
IMA ART works with private clients seeking a highly personalized approach to fertility, IVF and surrogacy, including individuals, couples, international intended parents and high-net-worth and ultra-high-net-worth families.
Our model is particularly suited to clients who value discretion, independent guidance, direct principal involvement and continuity across a complex family-building journey. Rather than managing a high volume of engagements, IMA ART deliberately limits the number of clients it serves so that its principals can remain personally involved throughout each relationship.
How long does the surrogacy process take?
A surrogacy journey commonly extends well beyond the nine months of pregnancy. The timeline can include IVF and embryo creation, surrogate search and matching, medical and psychological screening, legal agreements, preparation for embryo transfer, pregnancy, delivery and postpartum coordination.
The length of each stage varies according to embryo readiness, surrogate availability & matchability, medical circumstances and the requirements of the intended parents. IMA ART coordinates these stages as one continuous journey rather than treating matching, embryo transfer and pregnancy as separate events.
Does IMA ART work with international intended parents?
Yes. IMA ART works with intended parents throughout the United States and internationally. Based in Beverly Hills, California, we coordinate fertility and surrogacy journeys that may involve intended parents, fertility clinics, embryos, surrogates, attorneys and other specialists located in different states or countries.
International surrogacy can introduce additional legal, citizenship, immigration and logistical considerations. Where these issues arise, IMA ART coordinates with appropriately qualified reproductive and immigration attorneys and other specialists so that jurisdiction-specific questions are addressed by the professionals responsible for them.
What is Fertility Governance?
Fertility Governance is IMA ART's framework for bringing greater structure, continuity and informed decision-making to complex fertility and surrogacy journeys.
Medical treatment, embryo strategy, surrogate selection, reproductive law, psychological support, insurance and other considerations are often handled by different professionals. Fertility Governance considers how those decisions relate to one another, helps identify potential risks and maintains continuity across the family-building journey while each specialist retains responsibility for their respective area of expertise.
