Ad Astra in Baltimore: Professional Translation for Legal, Medical, and Business Documents
Ad Astra is a document translation service based in Baltimore that specializes in legal, medical, and business materials, with particular strength in Spanish, Mandarin, and French. The firm operates on a project basis rather than retainer, pricing by word count and turnaround time, and serves individual clients, law firms, hospitals, and mid-size companies across the Mid-Atlantic.
What Ad Astra actually does
Ad Astra handles certified translations—the kind required for court filings, immigration petitions, medical records, and contracts where accuracy carries legal weight. The service does not offer interpretation (live conversation), marketing translation, or literary work. The firm employs translators with subject-matter expertise: medical translators hold healthcare credentials, legal translators have paralegal or legal backgrounds, and business translators specialize in finance or technical fields. This specialization matters because a mistranslation in a medical chart or contract clause can create liability, and Ad Astra's model assumes the translator's domain knowledge reduces that risk.
The company operates entirely in-office in Baltimore; there is no remote-only model, and all work stays within the firm rather than being outsourced. Turnaround ranges from 48 hours for urgent work to 10 business days for standard projects. Rush fees apply for anything under 72 hours.
Services and pricing
Ad Astra charges by the source word (the original language document). Standard rates run $0.12 to $0.18 per word depending on language pair and subject matter; Spanish-to-English medical translation sits at the lower end, while Mandarin legal work commands the higher rate. A 5-page medical history (roughly 1,500 words) costs between $180 and $270 at standard rates. Certified translations, which include a notarized statement of accuracy and are admissible in court, carry a $25 certification fee per document on top of the per-word charge.
Rush work (48-hour turnaround or faster) adds 25 to 50 percent to the base rate. A same-day translation of a 500-word immigration petition in Spanish would run roughly $80 at standard rates plus 50 percent rush premium, totaling $120 before certification.
Ad Astra quotes projects by email or phone before accepting them; there is no online calculator. The firm does not charge setup fees or require minimum project size, so a single-page document is as welcome as a 50-page contract. Confirm current rates before requesting a quote, as pricing adjusts annually.
How Ad Astra compares to other Baltimore options
Baltimore's translation landscape divides into three tiers: large national agencies (often outsourcing work and charging markups), individual freelance translators (low cost, variable quality, no certification infrastructure), and small local firms like Ad Astra.
The national agencies—companies like Lionbridge or SDL—operate through Baltimore-area contractors but charge 40 to 60 percent premiums over Ad Astra's per-word rates because they add project management and liability layers. They suit clients who need a single point of contact for mixed-language projects or who want vendor-of-record status for compliance. Choose them if you need invoicing to a corporate account and are willing to pay for that convenience.
Freelance translators on platforms like ProZ or Upwork undercut Ad Astra by 30 to 50 percent but offer no certification, no quality guarantee, and no recourse if a mistranslation causes problems. They work well for internal documents, casual communication, or budget-constrained work where errors carry no consequence. For anything legal, medical, or business-critical, the freelance route is a liability.
Ad Astra's advantage is mid-market pricing with small-firm accountability and subject-matter expertise. The translator's name appears on the certification, which means someone with actual credentials stands behind the work. The firm is small enough that the same translator handles your project from intake to delivery, reducing handoff errors.
Who Ad Astra suits and who it does not
Ad Astra works best for individuals navigating immigration (visa petitions, birth certificates, marriage records), law firms preparing discovery or filing foreign litigation, hospitals translating patient intake or medical histories, and small businesses localizing contracts or regulatory documents. If you need a single certified translation of a defined document, Ad Astra's project model is a clean fit.
Ad Astra does not suit clients who need ongoing interpretation (doctor's appointments, court proceedings, business meetings). The firm does not provide those services and will not refer you elsewhere. It also does not handle marketing translation, where tone and cultural adaptation matter more than word-for-word accuracy, or high-volume production work where you need turnaround measured in days across dozens of documents; the firm's in-house capacity limits throughput.
What the first visit involves
Contact Ad Astra by phone or email to request a quote. Have the source document (or a scan) ready. Provide the language pair, subject matter, and target date. The firm will respond with a price and estimated turnaround within one business day. If you accept, you submit the document and pay upfront (credit card or bank transfer accepted). The translator completes the work and delivers a PDF, usually via email. For certified translations, you receive a notarized original on letterhead; pickup is available at the Baltimore office, or the firm mails it for a $10 fee.
There is no in-person consultation unless the document is complex enough to warrant a phone call clarifying scope. Most projects happen entirely remotely.
Hours, parking, and logistics
Ad Astra operates Monday through Friday, 9 a.m. to 5 p.m. Eastern Time, with limited Saturday availability for rush jobs (confirm in advance). The office is located in Canton, with street parking available; there is no dedicated lot. Mailing address and phone are on the website. Email quotes typically return within 24 hours on weekdays.
Ad Astra earns its place in Baltimore's professional services by combining certified accuracy with local accountability and subject-matter depth at a price point between freelancers and national chains, making it the practical choice for individuals and firms who cannot afford mistranslation.
