Collab Fertility, located at 2700 Ygnacio Valley Rd, Suite 170 in Walnut Creek, California, is an independent fertility practice serving patients in the East Bay, Contra Costa County, and surrounding Northern California communities. The Ygnacio Valley Rd address is in the heart of Walnut Creek's medical corridor — accessible from I-680 and a short walk from the Walnut Creek BART station, giving the clinic strong transit connectivity to Oakland, San Francisco, and the broader East Bay. California patients seeking additional providers can visit the California fertility clinic directory.
Physicians and Clinical Team
Collab Fertility is built around a collaborative, patient-centered model of care — an approach embedded in the practice's name and brand identity. The clinic's physicians are fellowship-trained reproductive endocrinologists who hold or are pursuing ABOG board certification in the subspecialty. REI fellowship training encompasses three years of intensive subspecialty education following OB/GYN residency, covering ovarian stimulation pharmacology, IVF laboratory science, surgical management of pelvic pathology, and the endocrine conditions that underlie reproductive dysfunction.
The clinical team at Collab Fertility is structured to reflect the practice's collaborative philosophy: patients work closely with a consistent team of physicians, nurses, and coordinators who function as an integrated unit rather than a fragmented assembly of specialists. This team-based approach is designed to improve communication, reduce errors, and ensure that patients feel genuinely supported rather than processed. The East Bay has a high proportion of medically literate, research-oriented patients — professionals in biotech, academia, and tech — and Collab's evidence-based, transparent care model aligns well with this population's expectations.

Laboratory and Success Rates
Collab Fertility's IVF laboratory is staffed by embryologists trained in the full range of in vitro procedures: egg stripping and maturity assessment, fertilization (ICSI or conventional), embryo culture through blastocyst stage, blastocyst grading and selection, biopsy for genetic testing, and vitrification. The laboratory maintains compliance with California Department of Public Health requirements and federal CLIA standards. California's large and competitive fertility market means that patients have options, and laboratory quality — reflected in fertilization rates, blastulation rates, and clinical pregnancy rates — is a meaningful differentiator.
Patients should review the most current cycle-level data published by the CDC's ART Surveillance program and the SART Clinic Summary Report.
Patient Experience
Walnut Creek is a prosperous East Bay suburb with excellent infrastructure, a walkable downtown, and the BART connections that make it a regional hub for Contra Costa County. The Ygnacio Valley Rd address is close to the Walnut Creek BART station, meaning patients from Oakland, San Francisco, Berkeley, and further points in the East Bay can reach the clinic by rail — a significant benefit in the Bay Area's traffic-heavy environment. For car-based patients from Pleasant Hill, Concord, Lafayette, Moraga, Orinda, and the Tri-Valley (Danville, San Ramon, Pleasanton), the I-680 corridor provides straightforward access.
The Contra Costa County patient population is diverse and affluent by national standards — a mix of tech workers, healthcare professionals, educators, and business owners who often bring significant health literacy and specific expectations to their fertility consultations. The East Bay also has a large and well-established LGBTQ+ community, and Collab Fertility's accessible, non-judgmental brand positioning aligns well with serving patients of diverse family structures. The practice's name and ethos — collaboration, transparency, partnership — suggest a patient experience that values shared decision-making and open communication.
Considering At-Home Insemination?
Not every fertility journey begins in a clinic. At-home intracervical insemination (ICI) is a lower-cost, private option that suits patients with no known fertility diagnosis — including single parents by choice, same-sex couples, and people who want to try a few cycles before committing to clinical treatment.
At-home insemination kits like those from MakeAMom come with step-by-step instructions designed for donor or partner sperm. Kits are a one-time purchase that can be reused until conception succeeds, require no clinic visit, and arrive in plain, discreet packaging. Many patients use them as a first step while working toward a fertility consultation — or alongside ovulation tracking while they wait for an appointment slot.
If you have a known fertility diagnosis, have been trying for 12 months without success (six months if you're over 35), or your physician has already recommended IUI or IVF, a board-certified reproductive endocrinologist is the right next step.
Insurance and Financing
California does not have a state-mandated infertility insurance benefit. Coverage depends entirely on the employer's benefit plan and the specific insurance product. The Bay Area's technology and biotech industry has led the way on fertility benefits nationally — major employers like Google, Apple, Facebook (Meta), Salesforce, and many others offer IVF coverage and egg freezing as part of their benefits packages. However, many patients in the East Bay — working in retail, healthcare, education, or small businesses — will not have these benefits and will face largely out-of-pocket fertility costs.
Out-of-pocket IVF costs in the Bay Area tend to be on the higher end of the national range: $14,000–$20,000 per fresh retrieval cycle, with medications of $3,000–$6,000. California's competitive fertility market means that pricing is variable, and patients should request a detailed written estimate of all costs before beginning treatment. Collab Fertility can assist with insurance verification and financial planning, including referrals to healthcare financing programs. For patients who qualify, pharmaceutical manufacturer patient assistance programs can reduce medication costs.
Frequently Asked Questions
What does "collab" mean in the context of fertility care? Collab Fertility's name reflects its philosophy that the best fertility outcomes emerge from genuine collaboration — between patient and physician, between the clinical team members, and between the fertility practice and the broader medical community. In practice, this means patients can expect transparent communication, shared decision-making, and a team that functions as a unit rather than a series of separate encounters with different providers.
Is BART access to the Walnut Creek location practical? Yes. The Walnut Creek BART station is within a short walking distance of the 2700 Ygnacio Valley Rd address. Patients from Oakland, Berkeley, San Francisco, and other BART-connected stations can take the Yellow Line (formerly Concord) to Walnut Creek station and walk to the clinic. For frequent monitoring appointments during an IVF cycle, this transit access is a meaningful convenience.
Does the clinic see patients from Tri-Valley communities like Pleasanton or San Ramon? Yes. The I-680 corridor provides efficient access from Danville, San Ramon, Pleasanton, and Livermore to the Walnut Creek area. Patients in these Alameda County communities who prefer an East Bay specialist over a San Jose or San Francisco clinic will find the Walnut Creek location accessible.
How does the clinic's patient portal support ongoing communication? Like most contemporary fertility practices, Collab Fertility provides a patient portal for accessing lab results, imaging reports, appointment scheduling, and direct messaging with the care team. This infrastructure is particularly valuable during the stimulation phase of an IVF cycle, when bloodwork and ultrasound results are reviewed daily and protocol adjustments may be communicated on short notice. Patients should confirm portal capabilities and expected response times during the onboarding process.
