Women's Health Care Associates — Littleton / Lone Tree, CO

4.9 stars / 1,649 Google reviews — almost any OB/GYN group in the south Denver metro will tell you that patient experience is their top priority. Very few have 1,649 data points sitting next to a 4.9 average to back it up. Women's Health Care Associates (WHCA) does. That combination — high volume, high score, sustained over years — is how you separate a practice with a few delighted reviewers from one with a structurally good patient experience across thousands of visits.

This is the kind of listing that prompts a specific question from patients researching the Denver area: is this a fertility clinic, or is it something else? The short answer is something else — a large, all-female community OB/GYN group with fertility workup as part of its scope, not a standalone reproductive endocrinology practice. That distinction matters when you are deciding where to start. If you are comparing practices more broadly, our fertility clinics in Colorado directory lists the REI clinics alongside community OB/GYNs so you can see both options on a single page.

About the Practice

Women's Health Care Associates has served south Denver for more than 30 years. It was established in 1986 and has grown into a multi-physician, multi-location practice that now includes seven physicians, three nurse practitioners, and an all-female clinical and support staff. The practice belongs to the OB/GYN Affiliates network — a Colorado administrative group that provides scheduling and billing infrastructure while leaving clinical decisions with the practice itself.

WHCA operates two offices:

• Littleton (primary): 7720 S. Broadway, Suite 440, Littleton, CO 80122
• Lone Tree (satellite): 10107 RidgeGate Parkway, Evergreen Building, Suite 320, Lone Tree, CO 80124

Both offices use the same central phone line — (303) 795-0890 — and share the same clinical team rotating across locations. Hospital deliveries and inpatient gynecologic surgery happen at AdventHealth Littleton (formerly Littleton Adventist) and Sky Ridge Medical Center in Lone Tree. Both are respected regional hospitals with strong obstetric programs.

The physician roster, per the Colorado Medical Directory listing for the practice, includes Drs. Carolyn Abman, Catrina Bubier, Jamie Gilroy, Sarah Pucillo, Rayna Trietsch, Kathleen Watt, and the nurse practitioners Kathryn England, Arian Hilsendager, Jennifer Lake, Kathryn Wilde, plus a nutrition counselor (Stephanie Modica) on-site. Dr. Bubier is the physician most commonly identified with the practice's infertility and high-risk pregnancy focus. Patients should verify individual physician board certification through the ABMS Certification Matters tool before a first appointment — the public-facing practice materials describe the team as "board eligible or board certified" in OB/GYN without individual dates.

Services — Routine OB/GYN Plus Fertility Workup

WHCA's published scope spans the full arc of women's health from adolescence through menopause:

• Obstetrics — prenatal care, labor and delivery at AdventHealth Littleton or Sky Ridge, postpartum follow-up
• High-risk pregnancy co-management — with maternal-fetal medicine escalation at the hospital partners when needed
• Annual wellness and preventive care — well-woman exams, pap, pelvic, breast, STI screening
• Gynecologic surgery — minor and major procedures at both hospitals
• Contraception and family planning
• Hormone therapy for perimenopause and menopause — including a Biote bioidentical hormone replacement program at the Littleton office
• Infertility evaluation and initial treatment — a diagnostic workup that includes hormone panels, ovulatory assessment, semen analysis coordination, and cycle monitoring
• Timed intercourse and cycle management
• IUI — for appropriate candidates, with referral pathways for more advanced care when indicated

The practice has a documented referral partnership with Posterity Health, a male-factor fertility group, which is one of the more thoughtful arrangements a community OB/GYN can make: it means a couple's male-factor workup is not an afterthought or a "see a urologist somewhere" pointer.

What This Practice Is — and Isn't

This is the most important section of this editorial, because the 4.9-star rating will attract patients across the fertility spectrum, and the wrong match wastes time.

WHCA is a community OB/GYN group. Its sweet spot is annual wellness, pregnancy, gynecologic surgery, menopause management, and the first stages of a fertility workup — unexplained infertility, ovulatory dysfunction, PCOS, basic hormone panels, timed cycles, and IUI when appropriate. For many patients, a year or more of care inside this scope is exactly what is needed to either conceive or arrive at a clear diagnosis.

It is not a reproductive endocrinology practice. WHCA does not perform IVF, does not run an in-house embryology laboratory, does not offer egg freezing or donor eggs, and does not report outcomes to the Society for Assisted Reproductive Technology (SART). A board-certified reproductive endocrinologist — a physician who has completed a three-year fellowship in Reproductive Endocrinology & Infertility after their OB/GYN residency — is a different specialty with different training, equipment, and scope.

If you have been trying to conceive for more than 12 months (or 6 months if you are 35 or older), if you have a known diagnosis that requires ART (severe male-factor, blocked tubes, diminished ovarian reserve, recurrent pregnancy loss), or if a prior workup has already pointed you toward IVF, your next step is an REI, not a community OB/GYN.

Denver-area REI options to consider alongside WHCA include:

• CCRM Fertility — Lone Tree — the flagship of a nationally known REI network, headquartered just down the road from WHCA's Lone Tree office
• Conceptions Reproductive Associates of Colorado — a multi-site REI group with a Littleton satellite and SART-reported outcomes
• RMA of Colorado and other regional REI groups with Denver-area offices

You can compare all of them inside our Colorado fertility clinic directory. Reading IVF outcomes across clinics is its own skill; our guide on how to read IVF success rates walks through the three questions that actually matter before you compare clinic A to clinic B.

Patient Experience — Reading 4.9/1,649

Very few OB/GYN practices anywhere in the country hold a 4.9 across more than 1,600 Google reviews. The statistical math is unforgiving: as review counts grow, averages usually drift downward because the long tail of bad experiences catches up with the concentrated praise of early reviewers. When a practice holds 4.9 through four digits of feedback, it is telling you that the things that reliably tank healthcare ratings — long waits, rushed appointments, dismissive providers, billing chaos, poor follow-through on results — are not the dominant experience here.

For patients dealing with infertility specifically, the emotional texture of the clinical relationship matters as much as technical competence. Fertility care is full of test results that are sometimes discouraging, repeated early-morning monitoring appointments, and sustained uncertainty. A practice that consistently feels respectful and attentive is genuinely easier to navigate.

Worth noting: WHCA's clinical team is entirely female. Some patients in reproductive care have a strong preference for female providers; at WHCA that preference does not cost you anything in terms of clinical depth or hospital affiliation.

Colorado's Fertility Insurance Landscape

Colorado has done more than most states on fertility coverage — but with real limits.

The Colorado Building Families Act (HB 20-1158, signed in 2020 and phased into effect beginning in 2022) requires large-group health plans (generally 100 or more employees) issued or renewed in Colorado to cover the diagnosis of infertility, treatment for infertility, and standard fertility preservation services. Qualifying plans must cover up to three completed oocyte retrievals with unlimited embryo transfers, with single-embryo transfer when medically recommended.

The limits matter:

• Small-group plans (under 100 employees) are not required to cover IVF.
• Individual and marketplace plans are not required to cover IVF.
• Self-insured employer plans — which describes many of Colorado's largest employers — are governed by federal ERISA, not state law, and can opt out entirely.

In practice, this means a patient at a 200-employee company whose employer self-insures may have no more IVF coverage than someone in a state with no mandate at all, and a patient buying insurance on the individual exchange has none of the mandate's protection. Before scheduling any fertility consultation, call your insurance's member services line and ask specifically: (1) Is my plan subject to the Colorado Building Families Act? (2) What infertility diagnosis and treatment is covered? (3) What is covered for fertility preservation and medications?

Our fertility insurance mandates by state guide lays out the full legal landscape and where the loopholes are. For patients who discover they are paying out-of-pocket, IVF cost by state has Colorado-specific ranges for what diagnostic workup, IUI, and full IVF cycles typically cost.

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.

Frequently Asked Questions

Is Women's Health Care Associates a fertility clinic or an OB/GYN practice?

WHCA is a community OB/GYN group that handles the first stages of a fertility workup in-house — hormonal evaluation, ovulatory assessment, cycle monitoring, timed cycles, and IUI when appropriate — alongside its primary scope of obstetric, gynecologic, and menopausal care. It is not a reproductive endocrinology practice and does not perform IVF, egg freezing, or donor-egg cycles. Patients who need assisted reproductive technology are referred to a board-certified reproductive endocrinologist. Our Colorado fertility clinic directory lists the Denver-area REI options, including CCRM Lone Tree and Conceptions Reproductive Associates.

Does my insurance cover fertility services at WHCA?

It depends on your plan. Colorado's Building Families Act (HB 20-1158) requires most large-group state-regulated plans to cover infertility diagnosis, treatment, and preservation — including up to three oocyte retrievals with unlimited transfers. Small-group plans, individual plans, and self-insured employer plans are not required to comply. Call your insurer's member services line before scheduling a fertility consultation and ask specifically whether your plan is subject to the mandate. Our fertility insurance mandates by state guide covers the Colorado law and its exceptions in detail, and IVF cost by state gives out-of-pocket expectations if coverage falls through.

What are WHCA's two office addresses and which hospital do they deliver at?

The Littleton office is at 7720 S. Broadway, Suite 440, Littleton, CO 80122, and the Lone Tree office is at 10107 RidgeGate Parkway, Evergreen Building, Suite 320, Lone Tree, CO 80124. Both use the central phone line (303) 795-0890 and share the same physician team. Obstetric deliveries and gynecologic surgery are performed at AdventHealth Littleton or Sky Ridge Medical Center in Lone Tree, depending on the provider on call and the patient's preference. Appointments can be requested at whcaobgyn.com.

Editorial Note

Fertlo editorials are independent. We are not paid by the clinics we cover, and inclusion in our directory does not depend on advertising, partnership, or referral relationships. This review draws on the practice's public-facing materials, the Colorado Medical Directory listing for OB/GYN Affiliates: Women's Health Care Associates, the practice's Google Business Profile, and publicly available information on Colorado HB 20-1158 (the Building Families Act). Individual physician board certification should be verified through ABMS Certification Matters; provider rosters, phone routing, and insurance participation at community OB/GYN practices change, so confirm details at time of booking.
