My teen has been struggling with severe acne for a few years now. I have Kaiser, and honestly, their dermatology department has been a disappointment . So I decided to seek outside help, which I'm paying for out of pocket. TDC has been an absolute game changer for my teen. Her acne is FINALLY improving. The doctors and team are informative, patient, and helpful. read more

I'm following up on my previous review. The same night I posted it, Dr. Tomasian personally called me to discuss the issues I had been having. I do appreciate that he took the time to listen, and the conversation itself was positive. Shortly after, my prescription was finally processed, and I received it on 5/1/26. It was also refilled for future use, which I'm thankful for. However, it took nearly two months to straighten everything out before I was finally able to receive my prescription. However, the overall experience still leaves me genuinely concerned. It took me being unusually persistent and more forceful than I'm comfortable with just to get a response from the office, pharmacy, and insurance. That shouldn't be necessary for a patient trying to manage their healthcare. More importantly, this situation caused me a great deal of stress and anxiety and has negatively impacted my health. I already deal with high blood pressure, and this experience elevated it further, which is both troubling and unacceptable when seeking medical care. At this time, I'm giving a 3-star rating in recognition of the effort Dr. Tomasian made to personally address the situation. I may update this after future visits. I sincerely hope his office improves how they handle patient communication and follow-through so that no other patient has to go through a similar experience. read more

Dr. Tomassian and his staff are amazing! Everyone was very professional and took care of me right away. I've been struggling with eczema for a while, and I really appreciated that they offered solutions instead of just a temporary fix. I left with a treatment plan and am excited to see the results! read more

I had a bump that started growing near my bicep almost 2 years ago. It was benign, so my insurance wouldn't cover its removal. My friend referred me to The Dermatology Collective. First, the staff warmly greeted me as soon as I walked in. They were all super nice! I then saw Dr. Jones, who said she could remove the bump right then and there, and they could send it for a biopsy just in case. The procedure was quick and painless! The bump is gone and the scar is barely noticeable. One thing I really liked about this place was that they said the consultation fee would be applied to any procedure I had done. Other places charged a similar consultation fee but would not count it towards the procedure. On top of that, the total cost was significantly less than quotes I received from other offices -- I probably paid half of what I would've paid at the other places I called. Most importantly, I was seen by Dr. Jones, who is an MD. Other places want you to consult with their PA first. Needless to say I'll be coming here for all my skincare needs going forward. Thank you, Dr. Jones and team! read more

See all

Had a great experience visiting Dr T. The office is in a cool open concept shared space in Glendora. Very much a boutique aesthetic vibe. Dr was very smart and nice and eased my concerns with a skin issue I had. Also checked certain moles and gave his opinion. Would def recommend this dr for dermatology needs. read more

Doctor Chris and staff are amazing! I have Kaiser but they misdiagnosed my skin issue several times. I decided to go outside of my insurance and book an appointment with TDC. Immediately Doctor Chris diagnosed and took care of my issue and within a few minutes I was done. I felt at ease and comfortable and when I was done I had such a sense of relief in regard to my issue. I cant thank Doctor Chris and his staff enough! read more

Went in for treatment. Took care of me and what needed to be done will be back again thank you derm collective

I come here monthly for chemical peels and my skin has never looked so good. I hate to say my age, but people think I'm younger than I actually am thanks to my amazing esthetician, Denise! I totally recommend. She is truly great at what she does. Plus. this clinic is beautiful - clean, aesthetic, and modern. read more

Denise a wonderful person very knowledgeable, Also, front office is very helpful courteous.

Dr. Tomassian is very kind, professional, and truly cares about his patients. The staff is amazing and welcoming, and the office is extremely clean. He helped me get rid of black spots on my back and later treated a wart on my finger that was gone within a week. Highly recommend. read more

I love Denise! she completely transformed my skin for my wedding! I have cystic acne and I rarely get breakouts anymore. My skin is glowing and I feel more confident now without having to wear much makeup. She always has her little hand held fan ready for me because I am a baby and need it as my support fan :P. Highly recommend! read more

Every time I've came here I leave walking with my chin up and the best most positive self esteem. The staff are all so nice and accommodating. The doctors are great and down to earth! They've really set the bar high for their services! read more

Dr. Tomassian n' staff are amazing! Love coming here, always well taken care of. I had some skin tags removed, but had a stubborn one. Dr Tomassian took care of it - didn't feel a thing! read more

I had a fantastic experience with Dr. Tomassian and his staff. Everyone there is so professional and knowledgeable, from the moment I walked in I noticed how warm and welcoming the environment is and how attentive the doctor is. When I was leaving, the front office answered all my questions and made my next appointment in a breeze. It's rare to find a medial office where the staff leaves such a positive impression. Highly recommend this office!! read more

The office is gorgeous and impeccably clean. Most importantly, Dr. Tomassian is such a great doctor... a great listener."

I've always known that acne is never cured but can be controlled. For half of my life, I suffered from moderate to severe cystic acne. This is the type that is painful, lasts for weeks and often can cause permanent physical and emotional scars. The key is finding a skincare regimen that your skin will respond to and finding a team who can help accomplish this! Since 2007, I have been under the care of Denise and she is the only person I trust with my skin! That speaks volumes because I was not blessed with glass/porcelain skin. It has definitely been a journey to get to where I am now, as I have tried everything. Yet, the regimen that I've had with Denise is what works, as my acne is under control! This includes peels, extractions and steroid shots. She has a gift when dealing with those pesky painful bumps. I have not scarred! I'm happy that Denise is now at Dermatology Collective because she is now part of a great team led by Dr. Tomassian. He's amazing at what he does too! He has really rejuvenated my skin by way of Microneedling with RF (added to my regimen). This place should be on everyone's list, if you want professional, knowledgeable and caring providers. -Earl (also posted via Google) read more

Came in here last week for an annual skin check. I grew up a river rat and spent most of my childhood on a boat in a lake, with no sunscreen.. thanks mom!! I have plenty of strange looking moles & freckles. I got my skin checked, some weird old lady things frozen off and one weird mole scraped of and sent to pathology. After only 2 days, Dr. Tomassian called me to give me the good news. It was just a weird mole. Finding a Dr that calls himself (not another staff member) with good news instead of only bad news is rare. I appreciate that a lot. Today I came in for some Botox it's been almost two years and it was definitely way over due. I like that the Dr does the injecting and he has a very soft hand. All of the girls in the office are very nice and helpful. I've gone to a few med spas that honestly I felt uneasy and unwelcome. The opposite happened here. I didn't feel like they were talking behind my back or giving me dirty looks. I felt like they were happy I was there and that means a lot! I will be coming here for all my old lady spots and wrinkle removing. Thank you Dr. Tomassian and your wonderful Staff! read more

It took me a long time to find a place like this! From the moment I walked Into their offices, I knew I had finally found a place I wanted and NEEDED to be. So KIND, so professional, so caring, so clean. Everyone! From the receptionists, to all the staff and Doctors. The prior dermatology office I went to obviously "non-diagnosed" my conditions, unfortunately for quite a while. From my very first visit with Dr. Gina Jones, I KNEW I was in the right place I was supposed to be. She was so very professional, kind, and thorough in my full body examination for possible skin cancers, that she made me feel positive I was going to finally get the car I needed. And YES, Dr. Jones did discover and diagnose more than a few "items" that definitely needed addressing and treatment. So thankful for THAT. When It came to treatment time, every visit, they make you feel welcome, comfortable, and safe with anything and everything they do for you. Dr. Jones did a beautiful job of excising my skin cancers. So "smooth", so gentle, so painless. Also, Dr. Hedayati did an amazing job on removing a cancer from my nose, and then reconstructing the area. As I stated previously, every single person in this office is kind, polite and professional as you can find , and I would recommend THE DERMATOLOGY COLLECTIVE to anyone and everyone..... In a heartbeat! read more

This doctor and staff addressed an issue I recently had within the hour I had it. Professional, prompt, and most importantly caring in a way that many offices are not. Take your kids here, you won't be disappointed. See them yourself, you'll be glad you did. read more

One of the best in the industry! Highly recommend The Dermatology Collective. Dr. T is very knowledgeable and realistic with his recommendations. Our forever family Dermatologist. Thanks TDC Team! read more

The staff are so nice. Dr Jones was quick and knowledgeable about my issues. I would definitely recommend them.

I really wanted to love this place and refer friends interested in getting Botox but I cannot recommend to anyone.(3 reasons) 1.I was overcharged for Dysport was told it is $5 a unit, but I only got 8 units and was charged for $120. I should have been charged $40. = They stole $80 from me. 2. I was ready to leave because there was so much going back and forth. My appointment was at 5pm I was still waiting at 5:50pm. So I go out to the desk to let them know I have other obligations I need to leave and the NP and workers are begging me to stay pushing me saying it will take less then 5 minutes. 3. I go back to sit down and the NP quickly injects me and I feel the dysport dripping down my cheek! So I got less than 8 units. This experience was a nightmare to say the least. They are not professional just money hungry. read more

I went here today for a skin treatment. Highly recommend them. Beautiful office. Nice and professional staff. I saw Dr. Mina, but both doctors are great. Can't wait to go back! read more

Hands down, the best dermatologist I've ever been to. My skin has never looked better -- people constantly tell me I have 'glass skin' now! Beyond the incredible results, the experience is just as amazing. They're kind, professional, and make you feel completely at ease. If you're serious about taking your skin to the next level, this is the place to go. I can't recommend them highly enough! read more

Very busy office, but they took good care of my husband and sent him to a really great surgeon for removing a questionable growth. If you have the time to wait, then I would definitely schedule an appointment with this office but do not expect a quick turnaround forgetting an appointment read more

I've never struggled with acne until this last year. I'd get blemishes here and there in high school but when I was a full year off of birth control, my face exploded. Painful, cystic acne covered my chin and cheeks. So bad, it would hurt to talk and move my face. I went from being a vibrant and confident 27 year old to hiding at home and avoiding any event I was invited to. I cried to my boyfriend daily about how I felt so unlike myself. I first sought treatment from a place called Beverly Hills rejuvenation center in Chino Hills. I'll save you the time, avoid that place at all costs. I spent ridiculous amount of money with them and my face was only getting worse. When I complained to them how bad it was getting and that I wanted to try something else they said "try not to stress, that's what's making it worse, and trust the process." Well after 3 months of trusting the process it only got worse and I looked elsewhere. That's when I found The Dermatology collective. I first started with Denise, who I actually used to see when I was a teenager for chemical peels. Not only was it nice to see a familiar and trusted face, she was raving about how much she liked the Dr. here than the previous place she worked for. After a few months of working with Denise, I set up a consult with Dr. Tomassian. I was very firm on not wanting to take any oral medications for my acne and while he was still encouraging it, he respected my choice and helped with alternatives. It's been 7 months now and my face is back to wear it was before the explosion and I feel like myself again. Some things I would like to highlight about my experience with TDC: 1. I never had to go out and buy ridiculously priced skin care products. Everything was sold at my local target/walmart. I didn't have to order any specialty things online or only sold at their clinic. 2. While there was a trial and error period the first month or so, I always saw forward progress. 3. Skincare and treatment is an investment, however their costs are fair and insurance is an option. 4. If I ever called in because of a bad reaction to a new treatment or a general concern, they didn't brush me off and got me back in to help right away read more

dr. Is more concerned about making TikTok's then getting to the root cause of any problem patient may have. Office is a mess. They lose your blood work and results. Never prepared just terrible. read more

ladies in the front office are so rude. The last time I went one of the ladies, the blonde one gave me attitude for no reason. Then the rest of the ladies followed laughing at me after she was rude to me. The doctor is great, but the ladies in the front should not be working if they don't like their job. If the doctor wasn't so good at his job, I would not come here again. read more

Great management and office personnel. All follow-up phone calls Are Much appreciated

Pretty sure I got asked four times how I did I hear about them and each time I said via my insurance's website. Even when they answered calls they ask "how did you hear about us?". The girls must have nightmares with that phrase. Went to visit this local dermatologist to get a second opinion on a skin condition that won't let me jumpstart my hot girl summer. The front staff, were incredibly friendly. The intake Lady and Dr. were also friendly. I appreciate him asking if I had other concerns before wrapping up. The process was quick even though I went in as a walk-in. I was in and out in under an hour, not bad tbh. New patient and follow ups noted on the intake forms were $150-$200 per visit. This obviously excludes prescriptions they recommended. I appreciate the transparency on paper. Definitely returning to look into skin cosmetic services and keep up with my flare ups. Thanks Dermatology Collective Staff! read more

I had such a pleasant first visit at The Dermatology Collective and with Dr. Tomassian! The staff was welcoming and helpful. The doctor listened closely, made me feel at ease, and quickly figured out a solution for my breakouts and rashes. The front desk was efficient with forms, payment, and booking my next visit--and they went above and beyond to help with my prescription despite some insurance issues. Really appreciated the care and attention from start to finish! read more

The Dr and staff are super caring!!!! I can't say enough about them! It was so nice to have such an amazing experience after we had a bit so wonderful experience with our old derm. This is our family's new dermatologist, for as long as they are in this location! I can't say enough good about them! read more

I seriously wish I was able to give more than 5 stars. I have a thing on my leg and I was worried it was skin cancer. I had googled Dermatologist for over a month and got no response back from any that I messaged. So I decided to check on Yelp and BAM I got a response ASAP from Dr Tomassian's office and was able to go in the very next day to get a biopsy done His entire staff is Awesome/Friendly and Very Helpful as you can imagine a cancer concern for us is very, very scary. All made me feel so comfortable and relaxed, Plus Dr Tomassian is Funny which is a Great attribute for a Doctor, this to me shows your not just a name on a file that your a person and that he genuinely cares about you and wants to make you feel at ease and comfortable  When I spoke to Dr Tomassian I could honestly hear the compassion in his voice as he was giving me my results and unfortunately it is skin cancer.   I can't say enough GREAT things about Dr Tomassian and his entire office. I Highly and Strongly recommend Dr Tomassian to ALL read more

Your staff is so amazing, kind and helpful... Dr.Tomassian is a wonderful dermatologist. I would refer everyone to him

Looks really nice inside out as many things to do and so far they've been really pleasant
