About Karla


Bio

Struggling with Nursing School? I’m here to help!
Hi there, I’m Karla—a Registered Nurse since 2015, nurse educator, and someone who gets it. I know nursing school isn’t easy. It’s overwhelming, fast-paced, and it feels like there’s never enough time to truly master the material. But here’s the thing: you don’t have to figure it all out on your own.

With a master’s degree in nursing education, years of bedside experience on a med-surg telemetry floor, and a track record of teaching...

Hi there, I’m Karla—a Registered Nurse since 2015, nurse educator, and someone who gets it. I know nursing school isn’t easy. It’s overwhelming, fast-paced, and it feels like there’s never enough time to truly master the material. But here’s the thing: you don’t have to figure it all out on your own.

With a master’s degree in nursing education, years of bedside experience on a med-surg telemetry floor, and a track record of teaching hundreds of students just like you, I’m here to help. Whether you’re in an ADN or BSN program, preparing for the NCLEX, or just trying to survive your next exam, I’ve been where you are—and I know how to guide you through it.
I specialize in breaking down those high-stakes topics that nursing students often struggle with (think Dosage Calculations, Arterial Blood Gases, Fundamentals, EKGs, Fluids & Electrolytes, pharmacology, and much much more!)

My approach? It’s all about you. I customize every session to your needs and learning style, helping you turn frustration into confidence. You can actually enjoy learning, finally!

A real RN helping out RNs in training

Karla has been a true asset for our foundation. She is helping 1st semester thru 3rd semester RN students enrolled in several different RN programs. She is absolutely a 10 out of 10. Highly Recommend

Great tutor

I can’t recommend Karla enough! Their guidance and expertise have been invaluable in my nursing studies. They break down complex concepts in a way that is easy to understand, making even the most challenging topics manageable. Their patience, encouragement, and in-depth knowledge have truly boosted my confidence. Thanks to their support, I feel more prepared and capable in my nursing journey. If you’re looking for a tutor who genuinely cares about your success, Karla is the best choice!”

Knowledgeable and very professional

Karla helped me to understand more about the cardiac system and fluid electrolytes. She explained very clearly. She was calm and very nice. She helped me with so many questions and she gave me extra information. Thank you Karla.

Silvana, 2 lessons with Karla

Patient and understanding

Karla listened to my concerns and asked what area I needed help in. She was able to break down the information and made sure we were on the same page. She explained in detail and gave me several examples on the subject we were reviewing.

Diana, 1 lesson with Karla

Knowledgeable and patient tutor.

I had only Wonderful tutoring sessions with Karla. She was extremely knowledgeable and very patient when explaining to me nursing material that I found complicated. Karla went over Respiratory and Oncology which were two subjects I have been struggling with in nursing school. I’m so happy to say that I passed my exams and my class and am very thankful for Karlas help!

Great Help!

Karla identified all the key information from each drug class to help make it less overwhelming. She also provided study aids!

Andrea, 5 lessons with Karla

Excellent Spanish teacher

Karla has been my spanish tutor for 3 months now. What started out as needing to learn Spanish for work turned into weekly lessons with Karla. She is extremely patient and has given me all of the resources needed to learn this language. It’s hard learning a new language as an adult but Karla makes it attainable. I would suggest her tutoring services to anyone.

Kristopher , 23 lessons with Karla

Listened to my goals, and didn't mind my tangents.

We started learning verb conjugation for conversational Spanish, with a goal toward Medical Spanish. She was excellent, and works in the same field, so I know she will be helpful.

Heidi, 10 lessons with Karla

Knowledgable and helpful tutor

Karla did a great job explaining and teaching the material in a way that was easily understood. She clearly has great experience and knowledge that helps her to be such a great tutor. Karla helped me through our advanced nursing course which included perfusion, cellular regulation, metabolism...etc. I will definitely be using Karla again while preparing for the Nclex!
