Jie Deng, MD PLLC — An Honest Editorial Review
Jie Deng, MD PLLC — which practices publicly as Think Fertility — is an independent reproductive endocrinology and infertility (REI) clinic in downtown Bellevue, Washington. Unlike many solo OB/GYN listings that appear in fertility directories, this is a full-scope fertility practice led by a fellowship-trained, double-subspecialized physician-scientist with an on-site embryology lab. It is a reasonable option for patients across the greater Seattle and Eastside metro who want a smaller, physician-owned alternative to the larger regional REI groups. If you are still weighing clinics across the state, our broader directory of Washington fertility clinics is a useful starting point.
Training and Credentials
Dr. Jie Deng earned her MD and PhD at Sun Yat-Sen University of Medical Sciences in Guangzhou, China, completed OB/GYN residency at Wayne State University, and went on to complete two ACGME-accredited subspecialty fellowships: Maternal-Fetal Medicine at Yale University School of Medicine, followed by Reproductive Endocrinology and Infertility at Stanford University. She lists FACOG and HCLD (High Complexity Laboratory Director in embryology) credentials — a relatively uncommon combination that means the same physician overseeing patient care also directs the lab. Board status should be confirmed directly at the ABOG Verify-a-Physician tool. Her NPI is 1578876199 (primary taxonomy 207VE0102X, Reproductive Endocrinology), and she is affiliated with Overlake Medical Center. Peer-reviewed work on PGT-A in poor responders, ICSI vs. conventional IVF aneuploidy rates, and culture-media comparisons is indexed on PubMed.
Services and Specialties
As a full REI clinic with on-site lab, services include:
- IVF including conventional, natural, modified natural, and mild-stimulation protocols
- IUI (intrauterine insemination) with partner or donor sperm
- Egg freezing (elective and medical fertility preservation)
- Donor eggs and third-party reproduction coordination
- Preimplantation genetic testing (PGT-A and PGT-M) and embryo biopsy
- Male and female fertility workup; diagnostic hysteroscopy and HSG coordination
- Management of PCOS, endometriosis, recurrent pregnancy loss, and reproductive endocrine disorders
Mandarin and Cantonese are spoken in clinic, which is meaningful for many Eastside families.
Success Rates and Lab Quality
For smaller independent clinics, always request the current SART member report directly from the practice and cross-reference it at SART and the CDC ART National Summary. Interpret any single-year number in context of cycle volume and patient-age mix — our guide on how to read IVF success rates explains what "per-transfer" vs. "per-cycle-start" actually mean, and why HCLD-directed labs with modern time-lapse incubators can meaningfully affect blastocyst yield.
Patient Experience and Bellevue Access
A 4.8 average across 82 Fertlo reviews is a strong signal for a single-physician practice — it suggests consistent bedside manner and follow-through, which are the patient-experience variables most often cited in negative fertility reviews of larger groups. The clinic sits at the 116th Ave NE corridor in downtown Bellevue, two minutes from I-405 and roughly 15 minutes from Seattle via SR-520 or I-90 outside of rush hour. Patients who want to compare or obtain a second opinion nearby can consider Pacific NW Fertility (Seattle), Seattle Reproductive Medicine, or Overlake Reproductive Health.
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 are over 35), or your physician has already recommended IUI or IVF, a board-certified reproductive endocrinologist is the right next step.
Insurance and Cost in Washington
Washington is a non-mandate state for IVF coverage — private insurers are not required to cover IVF, and most plans will not unless purchased by a self-insured employer that opts in. See our 2025 fertility insurance mandates map for details, and compare typical cash-pay IVF pricing at the IVF cost by state comparison. Ask Think Fertility directly about package pricing, financing, and multi-cycle discounts.
