Reviews
Independent review platforms, what the patterns say, and how we think about negative reviews. Links to the platforms patients actually use.
Reviews of Dr. McMillan and Synergy Spine Center are aggregated on multiple independent platforms — Google Business, WebMD, Healthgrades, Vitals, and others. Each platform has its own review collection and moderation policies; we don’t curate them. Patients can read across platforms to get a fuller picture than any single source provides.

Looking across platforms, certain themes recur in patient reviews. Patients describe the practice as small and personal, with the surgeon directly involved in pre-operative discussion and consent. The transparent pricing model gets noted favorably; surprise bills are a frequent complaint about hospital-based spine care, and patients appreciate not having that experience here.
Recovery descriptions in reviews align with surgical literature for endoscopic decompression — most patients describe meaningful relief within days to a couple weeks. As with any procedure, there’s variation; some patients describe slower recovery or partial response. Reading the full range of reviews — positive and less positive — gives a more accurate picture than any selection.
Negative reviews of any spine practice fall into categories. Some describe real disappointments — outcomes that didn’t match expectations, communication that fell short, costs that surprised. Some describe patient situations the practice wasn’t able to help (cases outside our procedure mix, situations where the underlying pathology wasn’t appropriate for the offered procedures). Some reflect honest mismatches between what the patient hoped for and what the procedure actually does.
We take negative reviews seriously when they describe specific addressable issues. We don’t try to remove or contest them as a matter of practice — that’s not the patient’s responsibility, and the integrity of the review platform matters more than the score.
Reviews are one input. Credentials are another. Dr. McMillan’s board certifications, fellowship training, and active licensure are independently verifiable through state medical board databases. Hospital affiliations and surgical privileges can be verified through the respective institutions.

Information here is educational. Individual results vary. Specific diagnosis and treatment decisions require evaluation by a qualified physician familiar with your case.Patient reviews of the practice are available on multiple third-party platforms. Google: search “Synergy Spine Center Seneca SC” — Google Business Profile reviews are the most comprehensive public source. WebMD: Dr. Marion McMillan’s WebMD profile aggregates patient ratings. Healthgrades and Vitals also maintain physician profiles with patient ratings. Each platform has its own moderation policies; the practice doesn’t have editorial control over third-party reviews.
The practice does not pay for reviews, does not offer incentives for positive reviews, and does not filter or selectively post reviews. The federal FTC Endorsement Guides govern what’s permitted in physician marketing — paid testimonials must be disclosed as such, and selective posting of favorable reviews can constitute deceptive practice. The practice follows these standards strictly. For first-party patient stories with HIPAA-authorized publication, see /patient-stories/.
Reviews on third-party platforms occasionally include criticism — sometimes about wait times, scheduling, billing communications, or specific patient interactions. The practice takes negative reviews seriously and addresses them through direct patient contact when patients identify themselves and the office can engage with the specific concern. The practice doesn’t respond publicly to third-party reviews in ways that could compromise patient confidentiality — HIPAA constrains what can be said publicly about any individual patient experience.
If you’re a patient who’d like to leave a review, the Google Business Profile and WebMD are the most-visited destinations. For patients who want to share a longer story for the practice’s patient stories page rather than a third-party review, contact the office through the standard contact channels. For complaints or concerns about your care, please call the office directly first so we can address the specific issue.
Reviews on independent platforms — Google Business Profile, WebMD, Healthgrades, Vitals, and similar — are collected and displayed by third parties without the practice’s editorial control over content. This makes them more credible than testimonials the practice publishes directly, but it also means the practice cannot correct factual errors, address specific concerns raised in reviews, or provide context that the review might benefit from. Reviews are what they are — a public record of patient experience without curation.
Google Business Profile is generally the highest-volume review platform for medical practices and is the platform most patients check first when researching a practice. The Synergy Spine Center profile can be found by searching “Synergy Spine Center Seneca SC” on Google. WebMD’s physician profile for Dr. McMillan is at this WebMD link and includes patient ratings across dimensions like communication, wait time, and outcome. Healthgrades and Vitals maintain similar profiles with independent patient ratings.
Reading reviews productively: Look for volume first — a practice with three reviews doesn’t have enough patient-experience data to be statistically meaningful; a practice with hundreds of reviews across several platforms has enough data to evaluate patterns. Look for patterns rather than individual reviews — one exceptional or terrible review is an outlier; consistent themes across many reviews reflect the practice’s actual character. Look for the specific complaints in negative reviews and whether the practice’s response (if any) addresses them substantively. And look at review dates — a practice’s character can change over time as staff, leadership, or facilities change.
The limitation of any review system: reviews skew toward extremes. Patients who had exceptional experiences (very positive or very negative) are more likely to leave reviews than patients who had unremarkable experiences. This creates a bimodal distribution that doesn’t reflect the practice’s average experience. For a more representative view, patient stories curated with FTC-compliant disclosure at /patient-stories/ supplement independent reviews. And for the most reliable information about whether the practice is right for your specific situation, the free MRI review followed by phone consultation provides direct evidence rather than second-hand testimonial.
