Adriana Monsalve

Emmy Award-Winning Sportscaster from Venezuela

Background

Adriana Monsalve is an Emmy Award-winning sportscaster from Venezuela with more than 20 years of experience in media. She wanted her English communication to reflect the same confidence and personality she has in Spanish.

What She Says

“After almost a year of sessions with Mary, I've improved tremendously, as a lot of native English speakers have told me lately. Mary has helped me learn to speak with better pronunciation since I'm not a native English speaker."

“Mary is transforming the way I communicate. I've improved my accent, and I've also learned to speak with better rhythm. The technique and tools she uses to teach are really professional and effective."

"She's the perfect coach to master your English communication skills. What can I say? I wish I’d found her sooner.”

Andrés Gonzalez

Software Engineer from Colombia

Background

As someone with a strong interest in languages, Andrés wanted to refine the finer details of his American speech and make his pronunciation sound more natural.

What He Says

"I'm a huge language nerd, and I really wanted to iron out some rough edges in my phonetics and my speech. She's been super helpful on that front because I've been able to focus on rhythm, cadence, and just even be laser-focused on some vowel sounds and specific phonemes that I've struggled with.

And working with her has made a huge difference at making them sound more natural and improving my overall accent and speech. She provides a lot of great feedback, and I think her knowledge of languages, or the English language, really shows."

 — Andres Gonzalez, Software Engineer from Colombia

 

 Written Testimonials

Lucile, Content Creator from France

★★★★★

"I've been working with Mary for around a year and a half, and I am so impressed at how much progress I've made.

I have a public facing job where I speak English all the time, and I feel way more confident about being understood.

Also, I regularly get compliments on my accent, which is always nice!

Mary is extremely detail oriented, she knows exactly what is going on with every little muscle in your mouth and how to position exactly to sound more American.

I am amazed at how much she knows and how she is able to convey that simply and efficiently."

Jacek, Software Engineer from Poland

★★★★★

"The Mary Formula is the way to go! I’ve been working with her for 7 months now and it has been a total game-changer. I honestly can’t believe the transformation.

Being a native Polish speaker, I can’t imagine being able to decipher all these sounds just by ear. The sessions are intensive and the training between lessons leaves my muscles sore, but... ever so slightly more capable :) We stick to the program but with a personalized approach to my first language's unique quirks.

Her meticulous eye (and ear!) for detail stands out more than anything else I could have expected. Most importantly, it works. I've noticed a difference in my speech fairly quickly and am excited for more!"

Cristina, Neurolanguage Coach from Italy

★★★★★

"I've been working with Mary for 5 months, and my accent has changed significantly! I'm a non-native English as a second language teacher and neurolanguage coach, and my goal is to provide the best service possible to my clients who are improving their English for work.
And Mary has helped me so much with that!

Before having classes with her, I was imitating the American accent without actually articulating the sounds as a native speaker. Thanks to Mary, now I know exactly how to move my tongue for each and every sound, and I'm also improving my intonation!

She is meticulous, patient, and passionate. She always finds a way to guide you through the sounds, even when it feels so difficult and different from what you're used to. 

I also appreciate our relationship so much: she is friendly, and we always have a lot of fun during our sessions! She is 100% the professional you're looking for if you want to sound like a real American."

Carlos, HR Business Partner from Venezuela

★★★★★

"I want to express my gratitude for the incredible coaching I've received over the past five months.

Working with Mary has led to a huge improvement in my English pronunciation and intonation. Her professionalism and attention to detail have made a significant impact on my accent reduction journey. The techniques she employs are truly the best I've seen, and each session has been immensely beneficial for me.

I especially appreciate her availability for feedback and her commitment to ensuring that I master every sound of the American English. She consistently goes above and beyond, which makes all the difference in my learning experience. Additionally, the content and videos she provides are invaluable for practice throughout the program.

Thank you for being such an outstanding coach and look forward to continuing working with you!"

César, Software Engineer from Mexico

★★★★★

"Working with Mary has been an excellent decision. As a native Spanish speaker, I wanted to develop a more American accent to gain confidence, be better understood, and improve my overall communication skills. Moving to the USA for a career opportunity made this essential. Mary, as an accent coach, has been invaluable. She provides personalized advice, high-quality materials, and comprehensive feedback.

Now, I am more conscious of mouth movements, the rhythm, intonation, and sounds of American English. As a Software Engineer, effective communication is crucial, and Mary's guidance has been very helpful. I enjoyed her sessions and highly recommend her coaching services to anyone seeking to refine their English communication and develop an American accent."

David, Software Engineer from Spain

★★★★★

"I have greatly benefited from Mary's English pronunciation lessons. Her expertise in identifying and addressing the specific challenges Spanish speakers face is remarkable. Mary's focus on detailed tongue movements and articulation has significantly improved my pronunciation.

Mary’s teaching methods are clear, patient, and practical. She effectively highlights the differences between Spanish and English pronunciation, providing examples and exercises that have helped me practice and understand these distinctions in context.

I highly recommend Mary to anyone seeking to enhance their English pronunciation skills."

Suyen, Client from Honduras

★★★★★

I have been studying English and pronunciation for many years and realized that to improve my pronunciation, I needed someone to help me. That's when I found Mary, and I am very happy I did! She has guided me in identifying the areas I need to focus on and why.

Previously, despite self-study, I was unaware of my specific mistakes and how to address them. Now, with Mary's guidance, I can recognize and improve those areas.

Another advantage is that Mary is fluent in Spanish, which allows her to explain English sounds more effectively to a native Spanish speaker. I highly recommend working with Mary if you want to take a significant step forward in your journey of learning English.

Lynn, Software Engineer from China

★★★★★

"Mary is amazing! I've been in the US for over a decade, but I still struggle with my accent, especially in professional settings or when speaking under pressure, like during presentations. Mary has exceptional expertise in coaching people with accents. She’s helped me speak with much more confidence while continuing to improve my clarity.

Beyond the regular class sessions, she provides access to a huge library of resources to study and review, which has been incredibly helpful. She also sets clear goals for each lesson and pinpoints exactly where I need to improve, making every session focused and effective.

She's incredibly responsive whenever I have questions and reviews my homework in great detail. I can’t recommend her highly enough if you’re looking for an accent reduction or speaking coach."

María, Client from Colombia

★★★★★

"After years of studying English and still struggling with pronunciation— to the point where I thought I had hearing issues or something wrong with my tongue— I discovered Mary, and working with her and her videos has been the best thing that ever happened to me.

I realized there’s nothing wrong with me— I just didn’t know how to use my tongue muscles or how to make the movements required to speak English clearly. By following all the information in her videos, I’ve been able to improve my pronunciation, and I constantly go back to review them because they’re so detailed, I don’t want to miss anything."

Katia, Google Content Moderator from Russia

★★★★★

"I've been working with Mary for a few months, and my accent has improved. Changing the accent is very challenging, and you must have a professional working with you. Mary is a trusted coach you can hire!"

Dmitry, IT Consultant from Russia

★★★★★

"I’ve been learning English on and off for over 30 years and have worked with many teachers, so I truly have something to compare with.

Mary is on a completely different level.

The quality of her teaching, the unimaginable amount of practical, well-prepared materials she provides, and her endless patience with mistakes are simply unmatched. Every lesson with her is genuinely enjoyable, inspiring and very result-oriented."
