The Sher Institute for Reproductive Medicine – Glendale (CHI) is a separate NPI-registered entity associated with the address 1520 Chevey Chase Drive in Glendale, California — the same physical location as the previously described Sher Institute for Reproductive Medicine Los Angeles Medical Group Inc. (also at 1520 E Chevy Chase Drive / 1520 Chevey Chase Drive — alternate spellings of the same street). The "CHI" suffix in this entity's name indicates a distinct corporate holding or management entity within the broader SIRM organizational structure, carrying its own National Provider Identifier (NPI) separate from the Los Angeles Medical Group Inc. entity at the same address. California does not have a state fertility insurance mandate. For broader California fertility clinic options, visit the California state directory.
How two entities share one address: It is not uncommon in medical practice for multiple legal entities to operate from a single physical address. In the SIRM network context, "CHI" likely refers to a different corporate layer — possibly a holding company, management entity, or a differently structured professional corporation variant — that billed or registered separately from the Medical Group entity. Each entity has its own NPI for billing and regulatory purposes, even though they operated at the same location and served the same Glendale patient community.
Note on operating status: The SIRM network underwent significant organizational changes in the 2010s and 2020s. Prospective patients should verify the current operating status of this Glendale location — and which entity, if either, is currently active — before scheduling an appointment.
Physicians and Clinical Team
Both the SIRM Los Angeles Medical Group Inc. and the SIRM CHI entity at 1520 Chevy Chase Drive / Chevey Chase Drive served the same Glendale patient community and operated under the same roof. The CHI entity distinction is primarily administrative and billing-related, not clinical — the physician team and physical practice were the same regardless of which NPI was used for a given billing transaction or registration period. Board-certified reproductive endocrinologists with fellowship training in REI staffed this location, working within the SIRM network's clinical framework.
From a patient experience perspective, the CHI vs. Medical Group distinction was transparent — patients received care from the same clinical team at the same address. The difference becomes relevant when researching outcomes data (different NPIs may be associated with different SART reporting entries) or verifying insurance participation (each entity may be enrolled with different insurers under its own NPI).
Services and Treatments
Consistent with the SIRM network at this address, the CHI entity historically offered:
- Fertility evaluation with individualized hormonal and immune assessment
- Ovulation induction and IUI
- In vitro fertilization (IVF) with personalized stimulation protocols
- Intracytoplasmic sperm injection (ICSI)
- Frozen embryo transfer (FET)
- Preimplantation genetic testing (PGT-A)
- Egg freezing for fertility preservation
- Recurrent implantation failure evaluation
- Immune modulation protocols
- Donor egg coordination
- Donor sperm coordination
- Gestational carrier management
Current service availability at the 1520 Chevy Chase Drive address depends on who, if anyone, currently operates at this location.
Laboratory and Success Rates
The IVF laboratory at 1520 Chevy Chase Drive served both SIRM entities at this address, as the physical laboratory was a shared asset of the Glendale practice. The CHI entity's NPI may appear separately in CDC ART or SART reporting systems, meaning patients researching outcomes for this address may find data under either the Medical Group or CHI entity name. Patients should review the most current cycle-level data published by the CDC's ART Surveillance program and the SART Clinic Summary Report.
Searching both the "Los Angeles Medical Group" and the "CHI" entity names in SART's online tool may yield different results reflecting different reporting periods or billing entities. The current operator at this address, if any, can clarify which historical data set best represents the practice at this location.
Patient Experience
As described in the SIRM Los Angeles Medical Group guide (the companion entry for the same physical address), 1520 East Chevy Chase Drive is in Glendale's established commercial zone, accessible from I-5, the Glendale Freeway (CA-2), and CA-134. Glendale's large Armenian American community, diverse general population, and proximity to Burbank, Pasadena, and northeast Los Angeles make this location convenient for patients across the northeastern Los Angeles basin.
The practical patient experience at this address — parking, neighborhood, clinical environment — is identical to what is described for the Medical Group entity, as both entities occupied the same physical space. Patients who previously received care or have stored embryos under the CHI entity NPI should use that specific NPI when verifying records, insurance claims, or cryostorage agreements.
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 fertility insurance mandate. As with the Medical Group entity at this address, patients seeking care under the CHI entity paid for fertility treatment out of pocket or through employer fertility benefits. The greater Los Angeles area's entertainment, technology, aerospace, and healthcare employer base includes some companies with voluntary fertility benefits, but coverage is far from universal.
The billing implications of two separate NPIs at one address include the possibility that each entity was enrolled with different insurers. Patients who received care under the CHI entity's NPI and are seeking to verify past claims, coordinate records, or continue care should use the CHI entity's NPI in all insurance and records inquiries.
Frequently Asked Questions
What does "CHI" stand for in the SIRM CHI entity name? The "CHI" suffix likely refers to a corporate holding or management entity — possibly "California Holdings Inc." or a similar administrative organization within the SIRM corporate structure. The exact expansion of the acronym is not publicly documented in standard NPI registry data, but CHI entities are a known pattern in multi-site healthcare practice ownership where different layers of the organizational structure are separately registered with the NPI. The clinical practice at this address operated under the same physician team regardless of which entity was billing.
If I had treatment under the CHI entity, how do I access my records? Patients seeking records from the CHI entity at 1520 Chevy Chase Drive should contact the practice or its current operator. If the practice has closed, medical records are legally required to be preserved for a defined period and should be retrievable through a successor entity or a records management service. Patients with stored embryos at this address should take immediate steps to verify storage status and arrange transfer if needed.
Are there two separate SART entries for the two Glendale SIRM entities? Potentially, yes. SART reports outcomes by NPI/clinic identifier, and two separate NPIs at the same address may appear as two separate entries in the SART Clinic Summary Report for certain reporting years. Patients researching historical outcomes data for this location should check both entity names. The clinical team at the current operator can advise on which historical data set is most relevant.
What Glendale-area fertility alternatives exist if the SIRM location is no longer operating? The greater Glendale/Burbank/Pasadena area has several fertility practice options within a reasonable drive. Practices in Pasadena, Burbank, and West Los Angeles serve the northeastern LA basin. The Fertlo California directory provides a current list of fertility clinics accessible from Glendale.
