Dr. Arthur Castelbaum, MD

Our appointments were easy and enjoyable. Dr Castbaum set me at ease

After having baby #1 via IUI under care of Dr. Freedman (who retired after), I had no doubts about working with RMA again for #2. Dr. Castelbaum brought us back up to speed on the process with confidence and care. When things took a little longer than last time, he informed us of our options but gave us space to decide how to move forward. And we were delighted to share our good news when it all worked out!

Got pregnant from my first round of IVF and received great personalized care under Dr. Castelbaum. I’m very happy and recommend RMA and Dr. Castelbaum to anyone needing fertility care.

Dr. Castelbaum and the entire staff over at RMA Langhorne were phenomenal. I have nothing but great things to say about everyone at that office. Dr.Castelbaum was very knowledgeable and encouraging to my wife. He put our worries and anxieties at ease with every visit. I highly recommend him to anyone going through the infertility journey. We began in January and we will be welcoming our baby girl to the world in April. Thank you RMA.

Dr. Castelbaum is a fabulous doctor!!!!! He answered all my questions, even stupid questions. He is always available for his patients!!!! These people with negative comments, are you sure you were seen by Dr. Castelbaum??? Your descriptions definitely don't match my experience with him. I am so happy Dr. took me in his care right away and was patient enough with my many questions. He always come in with happy mood, polite and explains everything!

Dr. Castlebaum diagnosed me with diminished ovarian reserve when I was 33 years old. He told me that I had “a less than 5% chance, but more like 0% chance” of ever getting pregnant with my own eggs. He then proceeded to make me feel like I was defective and joked that during the IUI process he didn’t “have to worry about over-stimming me” because my fertility markers were “abysmal”. Then he complimented my uterus and said my body was able to carry a baby but not conceive one. And that I had incredible health insurance that would make donor eggs very affordable (cha-Ching). He flat out told me there was no chance of me getting pregnant on my own. The week of my 35th birthday I conceived my first daughter naturally. I had a wonderfully healthy pregnancy and delivery. When my daughter was six months old, I got pregnant again, naturally and now have two daughters 15 mos apart. Beside being very wrong, this doctor was very condescending. Educate yourself if seeing him.

Dr. Castlebaum and the entire staff were incredibly warm and welcoming. They immediately put me at ease in what could have been a confusing and stressful time. They were informative and really make you feel cared for and listened too. They were also great about helping to navigate insurance and treatment costs. Highly recommend.

Hearing you need infertility treatment to become pregnant is beyond heartbreaking. After meeting with Dr. Castelbaum and his staff, my husband and I felt confident they would be able to provide us a family we’ve always dreamed of. The entire staff is beyond amazing from their compassion to their friendliness. They always made me feel important and comfortable. As I write this, I am currently holding my 2 day old daughter which wouldn’t be possible without them. Thank you Dr Castelbaum and RMA!

We were referred to RMA by my OBGYN office and cannot be more grateful for the experience. Dr. Castelbaum is beyond words. From the initial visit where we got to meet with him and begin discussing our options to our weekly appointments. Within our first couple of weeks he said I have no doubts you’ll Be pregnant in 3 months. Well almost exactly 3 months from our first appt we were pregnant! All of the nursing staff are incredible and sweet, and he just made this experience 10x better.

I highly recommend Dr. Castlebaum to anyone trying to conceive. When my husband and I first came to RMA we met with Dr Castlebaum, he made us feel positive about our situation. We chose to do IVF and it was the best decision we have ever made. We conceived on our first round of IVf, I am currently almost 10 weeks pregnant with my first child after almost 10 years of infertility.

Dr. Castelbaum has been amazing through every step of this process. Thankfully, my results were very positive, but I'm sure he would be caring in a less than positive situation as well. He was thorough, caring, and clear about each step. I was nervous about some of the more invasive procedures. He walked me through everything to help ease my nervousness. I would highly recommend that anyone seeking fertility counseling should see him.

Dr. Castelbaum is literally the most down to earth, and compassionate doctor I have ever come across. He does EVERTHING he can to make sure you are comfortable, well informed, and most of all ready! The staff at RMA is amazing as well. Everyone feels like family, the love you feel with this place is beyond anything I’ve ever experienced. Thank you Dr. Castelbaum, and RMA nurses for making our dream come true!

I LOVE Dr.Castelbaum!! I have always wanted to be a mother and he made that dream come true on my first cycle of iui with twins! I couldn’t be more over the moon happy about it. He is so personable and I really felt like he cared and was very genuine. He remembers everything you tell him! I don’t know how he does it. He truly is the best. I just couldn’t believe he made this happen on the first try. It’s amazing he has everything down to a science. Front desk &nursing are amazing to! Love them!!

Office staff was rude. Asked personal and invasive questions having NOTHING to do with the confirmation of my appointment. The office contacted me 6 times to remind me of my appointment but it wasn’t until the day of that they realized they don’t take my insurance.

He is the best! Super friendly, really cares about his patients. I went through 3 IUIs and a cycle of IVF he was very positive through our the whole process and now I’m 13 weeks pregnant after 3 years trying to concive. The wait time at the clinic was less than 10 mins they always call back the results within 1-2 hours. Staff and nusrses are so friendly. I don’t regret the whole experience love him. Best doctor again and again. :)

My husband and I had difficulty conceiving and based on all of the reviews, we ended up going with Dr. Castelbaum and I'm so grateful we did. After two attempts of IUI, we gave fertility treatment a break and actually conceived on our own. Dr. Castelbaum still monitored my pregnancy from weeks 5-9, rather than wait for my first OB visit at week 8. Staying with RMA for the first four weeks quelled so many of my fears and anxieties. I wish I could stay with RMA for all of my OB care, thank you!

I can’t overstate that choosing RMA and Dr. Castelbaum for our fertility journey was the best decision we ever made!!! I’ve truly never had another experience with a medical provider that has gone as smoothly as this has. I was treated on a personal level and always felt cared about and listened to. I was always able to get ahold of Dr Castelbaum via email or phone whenever I needed him. Most importantly we achieved success very quickly with RMA and are now expecting our IVF miracle baby!

Dr. Castelbaum is warm and friendly. He is very knowledgeable overall and is able to offer reassurance both emotionally and with medical facts. The nursing and doctor staff at RMA as a whole are wonderful. Even for monitoring appointments you see a doctor which made me feel like I was getting a lot of attention. A wonderful practice I would recommend to anyone struggling with infertility.

I was referred to RMA after having two consecutive ectopic pregnancies, while trying to conceive our second child. I went to RMA, had a fertility work up done by Dr Castelbaum, IVF was recommended. We went through our first cycle of IVF with Dr. Castelbaum, and I am currently 25 weeks pregnant after a successful first cycle. We look forward to returning when we are ready to conceive our third child.

It is difficult to put into words just how influential Dr. Castlebaum is each & every day. He builds positive relationships based on shared goals. His approach is filled with compassion, shared knowledge, and comfort. Dr. C's passion and expertise amazed me & my husband, and we can't imagine having gone through the journey with anyone else by our side. The staff at RMA provides exceptional service and prompt/open communication. Thank you Dr. C and RMA of Langhorne - you help to make miracles!
