Tanya’s Story

Throughout my entire childhood, I always thought I wanted to be a lawyer. I would practice litigation on my dolls and then later on with my friends.

I got married and gave birth to my first child while taking the LSAT's and applying to law schools. During that pregnancy, I gained 50 pounds! It didn't really bother me until I went shopping with a friend who pointed out that I was an extra large! That's when it hit me and I decided to lose weight. I started eating healthy and exercising a bit, and took some exercises classes here and there. I really liked the results and I continued to lose weight I never knew I even could lose!

After becoming a certified personal trainer and changing my college track to study nutrition versus law, I was giving fitness classes in a basement a few times a week when it suddenly became unavailable. I had less than one week to find a new space.

There was a storefront around the corner which was way too expensive and too big for what I needed and could afford. I took a leap of faith (or stupidity) and grabbed it, not knowing how I would ever make the rent. After a year there, I opened a similar space in Flatbush as well. Around this time, we also started filming and producing the Shape Kosher Workout DVD’s, the first and still the only Kosher Workouts for women. At that time, I only had one employee, a part-time receptionist, and was doing everything myself (and just had my second child).

After giving birth to my fourth child, Abby, I realized I needed way more help. Maybe it was the fact that I was working right in the delivery room or that I went back to work less than a week after she was born.

Either way, I realized that I definitely needed more help. This is when I met Rachel, a little 19 year old girl that came to my house for an interview in her pajamas and slippers. I hired her to help me in the office, babysit my kids, and take them to the library on Fridays (something I felt guilty about not doing since I was so busy). After a couple of months, Rachel became way more than a full-time employee. Plus, in case you’re wondering, she got a working wardrobe (bye pajamas!) and had no more time to take my kids to the library. With Rachel by my side, we went on to open the Williamsburg location in 2016. To make a long story short, with more amazing managers such as Alice and Basya who came along soon after, we went on to open Lakewood, Monsey, Monroe, Five Towns end even Israel. You can pretty much say that soon after giving birth to my 4th actual child, these other locations were born one by one.

After hearing over and over everyone’s requests to make and sell ready made food, we developed a food line called TAP (Tanya Approved Products) For a full catalog, click here.

Starting with just pastries such as muffins and cookies, it soon grew to ready-made meals and a variety of snacks. In 2019, the first cookbook Cooking with Tanya, came out and has since been a staple in many Jewish homes. We then came out with a Gluten-Free Cooking with Tanya cookbook, which serves a very big need and is the first healthy and gluten-free cookbook on the market.

I love knowing that we made it possible for so many clients to finally achieve their desired goals. A lot of people ask me if I practice what I preach and the answer is... Yes! I can go back to those "extra large" days very quickly if I let myself go and so, I work on myself every single day both with my eating choices and working out on a regular basis. Any advice I have ever given a client is something I would do myself.

I look forward to meeting you personally one day and having you be part of our Nutrition by Tanya family!
