Hi, guys, my name is Shruti, and I am happy to share that I have been admitted to the PhD program in Biomedical Engineering at the University of Houston, with a full scholarship! Let me be very honest: getting into biomedical fields in the USA is incredibly tough, and getting a full scholarship on top of that makes this even more special. This would not have happened without Dr. Parmar, sir, and his Letsdogre team.
Dr. Parmar sir did not delegate and disappear. He personally oversaw my application, resolved every doubt I had, and was always available when I needed clarity or reassurance throughout the process. I had applied to various departments and was genuinely confused about which one was the right fit for me. Dr. Parmar carefully analyzed my profile, interests, and strengths, and suggested the exact right department. That one decision led me to the prestigious Biomedical Engineering program. The right department, the right strategy, the right mentor. Everything came together, and I am now a fully funded PhD student in one of the most competitive biomedical programs in the USA.
If you have been told that without publications or a perfect profile, getting into biomedical engineering in the USA is impossible, I am living proof that the right guidance can change everything. Dr. Parmar Sir's experience, his strategic thinking, and the Letsdogre team's dedication can unlock doors you did not even know were open for you.

Today, I am deeply grateful to share that I have secured admission to the PhD program in Chemistry at Indiana University Bloomington with a full scholarship. This achievement carries profound emotional meaning for me, not only as an academic milestone but also as a testament to resilience, perseverance, and the right mentorship at the right time.

Throughout the application process, the Letsdogre team provided structured and strategic guidance. From carefully shortlisting universities aligned with my background in organic synthesis, radical chemistry, and polymer science, to meticulously refining my academic SOP, every detail was carefully crafted. They ensured my narrative reflected both my technical strengths and my personal journey.

What truly distinguishes Dr. Parmar Sir is not just his expertise but his genuine concern for students’ growth. Whenever doubts arose regarding documentation, timelines, communication with universities, or research positioning, the team responded promptly and professionally. Their clarity and experience significantly eased the complexities of international applications, especially after the challenges I had faced.

I wholeheartedly recommend Letsdogre to students aspiring to pursue advanced studies abroad. Their structured mentorship, personalized attention, and sincere investment in student success make them more than consultants; they become partners in your journey. For me, they helped transform a period of personal loss into a renewed path toward academic fulfillment and purpose.
