“Reena is intelligent, insightful, and easy to talk to!
Her passion is evident— she genuinely wants to help you and see you grow. She has loads of food ideas ready to share off the top of her head and I felt excited listening to these new easy and “actually” delicious meal options.
I was dealing with such bad stomach issues I had to eat pickled ginger throughout the day just to settle stomach…. Now my gut biome is so healthy and I never feel sick anymore!
She educated me by explaining the processes in my body, food, water, exercise, and other important principles I was not familiar with until working with her.
Can’t recommend her enough!! She will help you turn your life round one session at a time. I am very grateful to her and her help in taking this important step forward in my life and I encourage others to meet with her and transform the way I was able to! ”

Reena was great! After we introduced ourselves and she understood my goals, she immediately got to work creating a full meal plan for breakfast, lunch, dinner, and snacks. She made sure the plan included foods I already enjoy, suggested new foods I might never have tried on my own, and offered excellent snack ideas. I appreciated her balanced approach—she understood that I still like some less healthy treats and encouraged moderation instead of strict elimination. She even offered an exercise routine I can easily fit into my day.
What stood out most was how many options she provided, making healthier eating feel realistic and manageable. Her flexibility makes it easier to stick to a plan that supports both my weight-loss goals and a sustainable lifestyle change.
Overall, working with Reena feels like the start of a positive and achievable journey toward healthier eating and a healthier lifestyle.

Renna was wonderful. This was my first appointment with a dietitian as I’m navigating new auto immune diagnoses and symptoms. She listened to all my concerns, answered all my questions, and helped me build a sustainable meal plan.

Very helpful and clear communication, understood my needs and what I was looking for in terms of my personal goals! Made a basic meal plan to try out for these initial few weeks!

Working with someone like Renna is the equivalent of dropping tension from your shoulders. It's a relief to be supported by her.
I started seeing Renna around 3 months ago (feels like less!) after getting blood work back that indicated borderline prediabetes. I decided I wanted to reverse this since I'm so young. Renna assured me that all my diet needed was some tweaking, and we set up a few goals (portioning, exercise, etc). The first few weeks were an adjustment mentally and physically but Renna is truly here to cheer your on both during and between sessions. With just her tweaks, I've lost 9 pounds since Ive started working with her! I've never been able to lose weight before and honestly I'm of average weight so I wasn't prioritizing weight loss. I'm seeing a version of myself I didn't think was achievable and I'm really looking forward to all the other physiological and mental changes that have come from working with Renna.

Ms Shamah is an excellent registered dietician. I highly recommend her. She is very knowledgeable about nutrition and makes you feel very comfortable when speaking with her.

I just started my weight loss journey and I can already begin to see results.

Renna has been a tremendous help for my 10-year-old son, who is quite a picky eater. She took the time to understand his preferences and developed creative strategies to introduce healthier options in a way that he enjoys. Through fun cooking activities and appealing meal ideas, she made nutritious foods more enticing for him. Thanks to her guidance, my son is slowly expanding his palate and becoming more open to trying new foods. We're grateful for her support!

Working with Renna has been a total game changer for my weight loss journey! After years of trying different diets and getting nowhere, I finally found someone who understands nutrition in a way that feels sustainable and personalized. Renna didn’t just hand me a generic meal plan; she took the time to learn about my habits, preferences, and goals. She created a tailored nutrition strategy that fit my lifestyle, and for the first time, I felt like I wasn’t 'dieting' but actually making meaningful changes.

I cannot express how grateful I am for Renna's guidance on my fertility journey! After struggling for over a year, I reached out to her in hopes that a holistic approach to nutrition could make a difference. Renna took the time to really understand my unique situation, meticulously reviewing my diet and lifestyle. She created a personalized nutrition plan tailored to support my reproductive health and hormonal balance.
Within just a few months of following her advice, I started seeing improvements in my cycle and overall energy. Her expertise in fertility nutrition and unwavering support made me feel confident every step of the way. And the best part—I'm now pregnant! Renna’s knowledge, compassion, and positive energy truly transformed my life, and I’m beyond thankful for her help in making my dream of becoming a mom a reality. I highly recommend Renna to anyone looking for a nutritionist who genuinely cares and delivers amazing results
